Abstract
The utility model relates to a screw pump electric heating mated device for producing heavy oil, consisting of an electrical control cabinet (1), secondary cables (2), (4), a loop cable (3), a polished rod coupling (5), a transmission converter (6), a bracket (7), a torsion and pull bearing slip (8), a hollow polished rod (9), a driving head (10), a hollow sucker rod (11), a terminal (12), a conversion joint (13), a solid sucker rod (14), a rotor (15), a stator (16) and a guiding head (17). The device incorporates the screw pump and the electric heating device, wherein the screw pump with strong sand discharging capability can solve sand production problem, and the heating cable heats the heavy oil uniformly during the whole process. Therefore, the fluidity of heavy oil and the working conditions of the oil production machine parts are improved, the service life is prolonged, the normal production of oil well is ensured, and the utility model is suitable for extension and application.
Description
The utility model relates to a kind of process matched therewith device that is used for thickened oil recovery.
In the thickened oil recovery process, sand production is a great problem that has a strong impact on its ordinary production, and is then particularly outstanding for the new well of the firm operation phenomenon of shaking out.This situation even make and use in thickened oil recovery technology preferably that pit shaft hollow rod electric-heating technology also seems powerless adds that thermal effect is good again, and sand card phenomenon also can take place often, and the ordinary production of heavy oil wells in serious threat.For solving the heavy oil wells problem of shaking out, the on-the-spot screw pump that adopts at present demonstrates good result by force because of its sediment outflow ability, but, make ground control system part parts be damaged because of overload operation because the too high sand fluid flow resistance in pit shaft that contains of viscosity more often causes the pump of spraining.
The purpose of this utility model is to provide a kind of both can solve the problem of shaking out, and can effectively reduce oil viscosity and flow resistance thereof again, avoid the pump of spraining, and made ground control system part parts be damaged because of overload operation.
The purpose of this utility model is to provide a kind of both can solve the problem of shaking out, and can effectively reduce oil viscosity and flow resistance again, the pump and to the supporting thickened oil recovery device of the hurtful screw pump electrical heating of control system parts of avoiding spraining.
The utility model is to realize like this.This device by electrical control cubicles, secondary cable, return cable, send electric transducer, driving head, polished rod box cupling, support, bearing torque to bear slips, hollow polished rod, hollow rod, terminal organ, change snapping head, solid sucker rod, rotor, stator, guide head to form, its structure, assembled relation are as follows: the secondary cable that is picked out by electrical control cubicles is connected with the electric transducer that send that is installed in the well head top respectively with return cable, send the electric transducer seat to be placed on the support, support bears slips by bearing torque and is fixed on the driving head, drives headstock and is placed on the well head four-way; Secondary cable is lowered in hollow polished rod and the hollow rod that is attached thereto by polished rod box cupling centre bore, be connected to terminal organ under the hollow rod and become the snapping head, join with the solid sucker rod upper end that is connected to rotor down again, the rotor lower end is connected with guide head, and is provided with stator in the oil pipe at the corresponding position of rotor.During work, the subsurface progressive cavity lifting oil stream that constitutes by rotor, stator by cable, the power drive of sending electric transducer, driving head to transmit by electrical control cubicles, the cable that is lowered to simultaneously with it in hollow polished rod, the hollow rod heats oily stream, reduce viscosity of thickened oil and flow resistance, guarantee the heavy oil wells ordinary production.
The utility model adopts screw pump, electrical heating combination accessory device, collect the two and be one, the strong characteristics of screw pump sediment outflow ability both can have been brought into play, the solution problem of shaking out, can improve the mobile and oil recovery parts operating mode of viscous crude by heating cable to the omnidistance evenly heating of viscous crude again, increase the service life, guarantee the oil well ordinary production, be suitable for and apply.
Accompanying drawing is a general structure schematic diagram of the present utility model.Among the figure, label " 18 ", " 19 " are respectively well mouth of oil well blowout prevention box and well head four-way, and label " 20 ", " 21 " are respectively oil well casing and oil pipe, and label " 22 ", " 23 " are respectively oil pipe tail pipe and anchor.
Below in conjunction with accompanying drawing enforcement of the present utility model is illustrated.
As shown in the figure, the utility model by electrical control cubicles 1, secondary cable 2,4, return cable 3, polished rod box cupling 5, send electric transducer 6, support 7, bearing torque to bear slips 8, hollow polished rod 9, driving head 10, hollow rod 11, terminal organ 12, become snapping head 13, solid sucker rod 14, rotor 15, stator 16 and guide head 17 and form.Wherein, electrical control cubicles 1 adopts the frequency conversion electrical control cabinet of being made up of movement, housing, contactor, air switch, control panel, patchboard.Return cable 3 adopts the partial installation structural cable of being made up of Ф 8 core body copper rods, polytetrafluoroethylene (PTFE), tetrafluoro head, glass wool cloth, hollow stem, mica tape.Send electric transducer 6 to form by spy brush, collector ring, insulation wood.Bear bearing torque slips 8 and adopt the 42# manganese steel to make, the outside is rectangle, and the middle part is semi-annular shape, in the card tooth is arranged.Terminal organ 12 adopts 35# manganese steel to make, and is outside silver-plated.Other each component all adopt existing finished parts.
