Mathematical and numerical simulation of complex processes teplomassoperenosa at fluxion of multiphase medium in tubes of the output wells riged with arrays of electric-centrifugal pumps (UETSN), are one of the most effective and costeffective expedients of study of such holes, optimisation and subsurface equipment selection. Thus the hole and a bench represent uniform system that demands the registration of coherence of processes originating in them at problem solving of oil production, development and optimisation. The situation even more becomes complicated, if the hole with the vertical termination prizes a multisheet petroleum deposit, and in this case it is necessary to gain rated appraisals a rate of yield of each of pays or when the horizontal trunk of a controlled directional well goes on through a non-uniform bench on pattern and it is required to value an overall performance of separate leases of a trunk. Problem solving of the assaying and optimisation of operation of the down-the-hole equipment can be most effectively gained at presence vysokofunktsionalnogo repositories on fields, holes and a subsurface equipment.
Program-technical (ÅÆè ISKENDER complex is designed on the basis of up-to-date methods of mathematical and numerical simulation of the processes which are originating at driving of polyphase flows in tubes of a hole, the flowing channels of an immersion electric-centrifugal pump (ETSN) and a bench porous medium. In a bundle the uniform mathematical model of interdependent processes teplomassoperenosa in system «a bench - an oil-well - UETSN» is implemented. Makeup of software PTK ISKENDER go into:

The filtration sample piece of three-phase fluxion in a stratified-non-uniform bench in the presence of impermeable connectors between the pays, allowing at the given allocation of saturation capacities of water and oil phases to count fields of stress and velocities of phases in a bench, and also a fraction debitov fluids of each of the disconnected productive strata of a bench in the total rate of flow.
2. Mathematical models of fluxion of a three-phase mixture in tubes of a controlled directional well and in the flowing stages of the centrifugal pump, the mechanics of multiphase medium gained on the basis of the common equations and smoothing of performances of a mixture on cross-section of the flowing channels.

1. THE COMMON MATHEMATICAL MODEL OF PROCESSES
IN SYSTEM «THE OIL POOL - THE HOLE - UETSN»

The Instance of the specification statement of two-phase filtering in a bench. For calculation of performances of a two-phase filtration current in the stratified-non-uniform ­­­ bench prized by the vertical termination of a controlled directional well, the equations [1 - 3] immiscible liquids (water and oil) within the limits of large scale approach with allowance for coercibility of a porous medium and fluids in forgetfulness are used by force of gravity:

где - Stress, a water saturation and a vector of the total filtration rate,- Viscosity, velocity, the relative permeability to phase and coefficient uprugoemkosti i th phase (i=1 - oil, i=3 - water), K and m - absolute penetrability and dynamic porosity, f (S) - function of Bakleja-Leveretta (a water fraction in the total filtration current),- uprugoemkost medium c i th phase and a skeleton,- Values of the bound and limiting water saturation.

Water Downloading is carried out on a penetrable surface of an outline of G _p power supplies. In particular, at the assaying of a quasistationary environment of holes the equation (1) becomes divV=0. It is solved at stress specified values On a perforated surface of G _D an output well stope back. On boundaries of strata where absolute penetrability K suffers a breaking of the maiden sort, linking requirements are satisfied:Top of oil horizon and base surface are impermeable. If allocation of water saturation S on effective pays, the total mass influx G _D from a bench (rate of flow) and its water cut is setAre instituted as a result of the solution of a filtration problem (1). If a specified valueOn a bottom hole by means of function of Bakleja-Leveretta f (S) the saturation capacity field at first is deoxidated, and then pressure distribution, filtration rates of phases in a bench and a rate of yield of output well G _D is.

Three-dimensional filtering in a bench to the horizontal termination of a hole also is presented by the equations (1).

mixture Fluxion in a hole. Products arriving from a bench, moves to a land surface on controlled directional well tubes. Its piecewise linear profile is under construction on inklinometricheskim to the data and is characterised by variations of antiaircraft and azimuthal angles on well depth. At constructing of an one-dimensional sample piece of fluxion of a three-phase mixture along hole axis its three-dimensional profile is substituted by two-dimensional dissector in a plain with saving of length of leases of tubes and magnitudes of an antiaircraft angle. For calculation of the erected thermohydrodynamic processes in a hole the system of the differential equations gained by analogy with [4&nbsp is used; -   6] as a result of smoothing of the common equations of mechanics of multiphase medium on orthogonal hole axiss to cross-section:

It is supplemented to the proportions linking various performances of a mixture and phases:

Here Z - co-ordinate of the space fulcrum Oz passing through a mouth of a hole and having a kickoff on bed top;- Averages on cross-section f _K the channel gravity, the average velocity, a mass flow, the true and account volume contents of i th phase (subscripts 1, 2 and 3 fall into to oil, gas and aqueous phases accordingly); P, T, p, w, G - stress (equal to all phases), temperature, gravity, a rate of volume flow and a mixture mass flow; - Analogues of coefficient Zubera allowing for irregularity of allocation on cross-section f _K of velocity of a mixture w and volume true densities of j th disperse phase; v _j - its velocity of drift; a _PI , a _TI - coefficients of thermal expansion and cubical elasticity of i th phase; - Values of gravity of oil in the sheetAnd degassed oil in standard conditions accordingly; R - the universal gas constant, Z _g - a real gas supercompressibility factor, Q _v - referred to a mixture unit volume linear power proportioned along tubing strings (NKT) the exterior heat sources stipulated by losses of the electric power in a cable, feeding UETSN;- Averages on ambit of the channel a shearing stress and a heat density on channel wall; J - mass rate of formation of a gas phase at the expense of oil, referred to a mixture unit volume; L - a latent heat of dissolution of gas in oil; C _H - percentage by weight of the gas diluted in oil at stress P above stress P _H of saturation of oil by gas; F (P/P _H , T) - the generalised bubble-point gas-in-oil solubility factor; F ^* - a solubility coefficient at some representative value of temperature - A slope; V _o - the normal bulk of gas dedicated from an oil phase at - A gas density under normal conditions - An in-place oil gas factor at P = P ⁰ and temperature T = T ⁰ accordingly;- Bubble point pressure at - Coefficients; r _K - channel radius (value k=0 matches to a lease 0< z< Z _E the casing string of a hole below dot Z _E hangers of immersion array, k =1 - NKT at Z _E < z< H _c , H _c - co-ordinate of a mouth of a hole, r ₁ < r ₀ ); g - a projection of a vector of an acceleration due to gravity to fulcrum Oz; f (x, z) - angle of lean of a well section concerning fulcrum Oz.

Processes in UETSN. Calculation of processes teplomassoperenosa at mixture driving in channels ETSN and arguments of operation of separate stages is carried out on the basis of system of the differential equations [5, 6], extending the discrete schema of Item D and nbsp; Ljapkova and Century I and nbsp; Igrevsky [7]:

Here m - a fraction of the stages which have been gone on by a current; M - a total number of stages in pump knot; - A volume flow, head and a coefficient of performance, characterising operation of a separate stage at mixture pumping-over.

Mathematical models (2), (3) allow for the main effects originating at driving of a three-phase mixture in tubes of a controlled directional well and in the flowing stages of an electric pump: neizotermichnost, changes of phase, a friction, influencing of force of gravity, razgazirovanie an oil phase in a hole, gas dissolution in oil in pump channels, coercibility of phases, variation of structural moulding boxes of fluxion of a mixture, inverse of fluid phases and gas bypassing of dispersible components of a current, heat change with a circumambient. The equations (2), (3) as special cases include the equations uniphase (oil or aqueous) and two-phase (gas-oil or oil-in-water) streams in a hole and channels ETSN.

At pumping-over by the pump of nonuniform mediums arguments Operations of stages continuously vary from reception to mud pump discharge in amount of compression and mixture heat, and also free gas dissolution in oil. Interdependent variations of performances of a current originating thus and operation factors of stages along pump knot are allowed by a sample piece (3), therefore at its numerical implementation on each pitch Spacing division It is necessary to realise conversion of magnitudes . For definition of these arguments the formulas gained as a result of update of a design procedure of coefficients are usedThe relative head, feeding and efficiency, injected Items D and nbsp; ­ Ljapkovym ­[8], where- Feeding, head and efficiency of a stage by its operation on water. As have demonstrated special appraisals, over the range the relative feedings Both for laminar, and for turbulent flows head At pumping-over by a stage of a mixture by charge Q and effective viscosity With a margin error It is possible to compute under formulas:

Here - Passport values of feeding, head and efficiency by operation of stage ETSN in an optimum regime on water, - Coefficient of its rapidity, Angulator of rotating of the arbour of the pump (electromotor rotary table), v - coefficient of effective kinematic viscosity of a mixture. Magnitude depends on density of disperse phases in a current and it is instituted under formulas [5, 6] with allowance for effect of phase inversion.

At preset values of magnitudes on stage reception coefficients at first are computed , then appropriate arguments of its operation on water are instituted: feeding and head on a passport curve further by means of proportions (4) head is counted Stages at mixture pumping-over. We will note that unlike the method of application [7, 8] calculation of head of a stage under formulas (4) does not demand iterating.

Graphics of [7] semiempirical criteria dependences for a several representative value of the relative feeding q _B a stage the waters builted by Item D and nbsp; ­ Ljapkovym ­ on the basis of treating of numerous experimental data, are introduced on fig. and nbsp; 1 and 2:

For head conversion Stages from water on a non-uniform mixture out of a gamut We built the dependences analogous (4):

where q _Bmax - the relative maximum feeding of a stage on water, at which one head - values of coefficient

magnitude The relative efficiency at emulsion pumping-over over the range It is instituted by proportions [8]:

where - factors of the relative efficiency of a stage at the laminar and turbulent flows of a mixture, - The Reynolds number entered by Item D and nbsp; Ljapkovym. At small Reynolds numbers , when approximating (5) does not work, since values become negative, function is determined by proportions:

The Assaying of effects of calculations under formulas (5), (6) has demonstrated that performances of stages of various standard sizes by operation on a mixture are similar to performances of operation of stages on water, if at definition of conveyance factors

Power level N, consumable stage ETSN at emulsion pumping-over, is instituted by formula

- passport dependence of an input of a stage of the pump by operation on water gravity p _B . In the modified method of application of conversion of performances of a stage tendered by us from water on dependence emulsion are set as tabular functions of feeding .

Possibility of variation of environment UETSN by means of running ground station (for example, type "ELEKTON") is allowed in a sample piece (3) by means of dependences of arguments of operation of an electric-centrifugal pump and power consumed by the submersible motor, from frequency:

- performances of a stage and the array motor engine at the nominal angulator of rotating of arbour PED - analogous arguments in formulas (4) - (6) at

Linking mathematical models. Requirements of linking of solutions of set of equationss (1) and (2) link performances of a filtration current and a current in the casing string at z=0 on a bottom hole:

Requirements (7) allow to discover thermohydrodynamic performances of a mixture in the hole casing string on a lease From its stope back to co-ordinate z _E hangers UETSN. For linking of solutions of systems (2) and (3) on reception UETSN (on a going into pump a site at Z=Z _Э-0 ) requirements

are

Here flow parametres in dot Z=Z _Э-0 are from the solution of the equations (2) on a hole lease 0< Z< Z _E . Requirements (8) allow to solve the equations (3) and to discover performances of a three-phase current along stages ETSN, including - values on pump discharge. These magnitudes are for boundary values for a problem (2) at . appropriate requirements of linking in a dot (on going into NKT) look like:

On a hole mouth at z=H _c the boundary condition

Where P _lips - the given wellhead stress. Apparently, such posing demands the inverse problem solution, as generally magnitude Are unknown persons. The forward problem (1) - (9) is solved by finite difference method. For determination of the solution of an inverse problem (1) - (10) iteration methods are used. Appropriate numerical sample pieces and algorithms of calculation of processes in system «a bench - a hole - UETSN» are implemented in PTK ISKENDER.

The System of the is standard-referential information ( ) downhole equipment ensures with SiNsI stowage, treating and giving of a stationary value and the conditional-fixed information on downhole equipment. The system is intended for maintaining of the data about downhole equipment in an actual state, supplies of entirety, purification, monitoring of integrity and consistence of the data. The basic problems solved thus are:

• making of a uniform information field about used downhole equipment;
• the centralised administration of reference data;
• a support of multi-user distributed operation with reference books, including the territorially-remote subdividings;
• strictly regulated operatings on data modification.

Such approach allows to ensure:

• an urgency and reliability of the information on downhole equipment;
• optimisation of interchanging and a data storage about downhole equipment in the company;
• raise of operationability of the business processes using system;
• possibility of integration with operating intelligence systems;
• an einartig data display about downhole equipment.

SiNsI consists of two main bodies:

• a database (DB) for storing of information about downhole equipment;
• the client application intended for entering, editing and representation storable in a DB of the information on downhole equipment.

By operation from a DB the gang of the functionality guided on stowage and giving by means of requests of the information on downhole equipment, used in oil-extracting branch is afforded the user at an oil recovery. In a DB it is stored:

• the information on domestic and foreign producers of downhole equipment (for example, DIAMOND, ALNAS, BENZ, the FIGHTER, IZHNEFTEPLAST, novomet, CENTRILIFT etc.);
• the information on electric-centrifugal pumps (the naming, passport tabular performances of operation of a stage on water, optimum arguments of operation of an extent on water, geometrical arguments of a stage);
• the information about PED (the naming, rating data, geometrical arguments, coefficients of approximating of passport dependences);
• the information on knock-out boxs (the naming, rating data, geometrical arguments, coefficients of approximating dependences);
• the information on tubing strings (the naming, geometrical performances);
• the information on casing strings (the naming, geometrical performances);
• the information on cables for PED (the naming, geometrical performances, performance curves).

the Client application affords the user a gang of the functionality, allowing to run the data about downhole equipment. A row of standard operations over the data is bolstered:

• entering of the data in a DB with usage of dialog boxes and wizards;
• editing brought before the data in dialog boxes;
• review brought before the data in dialog boxes.

In the client application functionality of input, editing and review of any information are implemented:

• about the basic producers of downhole equipment;
• about stages ETSN (the naming, tabular performances of operation of a stage, its geometrical arguments, optimum arguments of operation of an extent on water);
• about PED (the naming, rating data, geometrical arguments, coefficients of approximating of passport dependences);
• about knock-out boxs (the naming, rating data, geometrical arguments and so forth);
• about tubing strings (the naming, geometrical performances);
• about casing strings (the naming, geometrical performances);
• about cables for PED (the naming, geometrical performances, performance curves).

The Data about performance curves affords the majority of producers in the form of a curve collection in a figure stored in a file of a plot format. Therefore for depositing of the data in a DB in makeup of the client application specially designed program tools are plugged, allowing to make correct transforming ("numbering") of a graphic information to a datasheet form. Numbering can be held by two expedients. In case of the former, when each of curves in a figure is continuous, monophonic and has characteristic colour, constructing of tables can be executed on the basis of discernment of diagrammes on their colour. Otherwise, and also when curves of performances are imaged in a figure by tokens, numbering is carried out with usage of cubical spline-interpolation on datum points set by the user.
Makeup of the client application go into:

Program moduli of transforming to a datasheet form of plot passport performances «feeding - head» and

• «feeding - power» by operation of stages of electric-centrifugal pumps on water. Dependence «feeding - boiler efficiency» is automatically counted under this data and is for monitoring of receivable tabular values.

Moduli of numbering of working rating data PED «shaft horsepower - boiler efficiency - a current strength - a sliding factor –».

By way of illustration on fig. 3 and 4 effects of a discernment of characteristic curves of the motor engine (98) 9ЭД63-103М and stages of pump ETSNM5A-160 by means of aforementioned moduli are resulted. The files containing plot working dependences PED or ETSN, boot in a DB for fixed stowage and program numbering. Its effects are imaged by tokens, fig. see; 3 and 4. In the same place the windows imaging the fields of a DB, intended for stowage and editing of the factory information of the concrete equipment are demonstrated. In reduced instances are the nominal arguments of operation PED, its leading dimensions, best values feedings, head and boiler efficiency of stage ETSN by operation on water etc. All this data are used at execution of calculations in PTK ISKENDER processes in system «a bench - a hole - UETSN» by means of a sample piece (1) - (10).

Integral part PTK ISKENDER are program moduli of the plot assaying of various input data and effects of numerical simulation of processes in system «a bench - a hole - UETSN». These tools are intended as for preparation of the appropriate data for rendition, and is direct their plot representation (for example, fields of stress, a water saturation of a bench, penetrability and porosity allocations and so forth). In a bundle moduli of freely propagated import visual analyzers ParaView, Tecplot are widely used. Along with them the characteristic subsystems of rendition allowing for singularities of differential problem solving on an irregular grid, and also three-dimensional nature of input data are designed also.

Some instances 2D and 3D maps are introduced on fig.   5  -   7. In bottom of figures it is resulted range of control of mapped function and a colour graphic pallet corresponding to it. A Fig. and nbsp; 5 illustrates not only pressure distribution on the floor space of the Muravlenkovsky field on some instant, but also a layout mining and injection wells.

On fig. and nbsp; 6 it is demonstrated 2D water saturation allocation in a vertical section of the bench prized by the horizontal termination of a controlled directional well and containing active bottom water. A Fig. 7 shows possibility of constructing of the map tools of bundle ISKENDER with usage of screens when the three-dimensional surface of function in the chosen circumferential neighborhood of a horizontal trunk is under construction not in all gamut of values, but only its certain part. It is the instrument it is specially friend for the plot assaying of the complicated non-standard allocations of magnitudes on a countable grid. In both figures the water cone organised in this case in a bench under the influence of a hole is well visible.

Let's esteem in the capacity of an instance assay values of operating conditions of operation of a controlled directional well of the Priobsky field riged UETSN. Array consists of the axifugal electric pump assembled from =300 stages SPI  D8-30, and electromotor EDB63-117V5. The Well section builted on ­ inklinometricheskim ­ to the data, is introduced on fig.   8а. The dot in a figure demonstrates rule UETSN. The hole prizes two effective pays width of 37 and 27 m accordingly between which one the impermeable connector (2) width 74 is laied out м. Absolute penetrability of pays 1 and 3 is equal 0.002 and 0.013 microns. At calculations a water cut volume flow holes on fluid under normal conditions as a result of the solution of a filtration problem bottom hole pressure P ₃ =10.2 MPa, and also the contribution of each of pays is discovered in the total rate of yield bench:

Rated operating points on integral performances are laied out out of the left domain boundary of optimum pump capacitys, fig. &nbsp see; 8б. It testifies to the wrong selection of array to a hole. Thus a gas content on pump suction compounds about 25 % (fig.   9) that is quite admissible for normal operation of the pump.

Fig.   8. A profile () a controlled directional well with the vertical termination and operating points of electric pump SPI D8-30-1450 on integral curves () head H _E , powers N _E and efficiency

A Fig.   9 illustrates representative allocations of some required functions of a three-phase water oil and gas current along a well bore. Apparently in a figure, at mixture driving in channels ETSN because of stress substantial increase there is the complete dissolution of the free gas phase in the oil derivated on a bottom hole. In the field of two-phase fluxion pressure distribution P has almost linear nature, and variation of temperature T in the core is instituted by heat change of a moving oil-water sludge with rocks enclosing a hole. Thus variation of the true water contents in a current there is owing to effects of coercibility and heat expansion of oil and water, and a magnitude it is refunded to a reference value

Fig.   9. Pressure distributions P, temperatures T, true volume
gas - and water contents и Along a well bore

Repeated razgazirovanie starts in NKT on depth of 820 m when stress P becomes less stresses P _H (T) saturatings of oil by gas. In process of a further decompression in a hole owing to a heat of products a gas saturation Sweepingly grows, attaining on a mouth almost 75 %. With magnification of the true gas content in a three-phase current intensity of chilling of a mixture is augmented, as the energy part is outlayed for gas phase formation. This effect stipulates variations of nature of the temperature curve, well visible on fig.   9. At When because of gas presence in a current gravity of a mixture p in NKT noticeably is moderated, varies also nature of dependence of stress P (z) - it becomes nonlinear.

We Will note that along with conducting of proximate analysis of an overall performance of system «a bench - the hole - UETSN», PTK ISKENDER allows to solve optimisation problems of current operating conditions of operation of output wells at the expense of the frequency running by means of land SOUS, and also to realise rational selection UETSN to holes for the given technological regimes of their operation.
