Abstract
The utility model relates to a downhole tool used for an oil well of an oil field, especially provides a bidirectional nozzle hydraulic injecting pump, which is composed of a diffusion pipe, a jet pipe, a formation liquid inlet, a driving nozzle, a power liquid flow path, an outer working drum, a sinking pump and a sand washing nozzle, according to the bidirectional nozzle, the sand washing nozzle and the driving nozzle adopted by the utility model, the power liquid enters into a pump suction port by the power liquid flow path after being inputted to the downhole by a double-pipe ring empty, one part of the power liquid is spurt out in the positive direction by the sand washing nozzle with the flow speed more than 100 m/s, the injecting flow is diffused in the well bore with the fan shape to enable the deposition sand at the horizontal segment to be sufficiently suspended in the sand washing liquid; the other part of the power liquid is discharged through the jet pipe to the diffusion pipe after being mixed with the power liquid sprout by the driving nozzle through driving the downhole injection pump to work by the driving nozzle to form the negative pressure at the well bottom, accordingly, the horizontal well negative pressure sand washing is implemented, the problems of the sand washings of large steepness well segment and the horizontal well segment can be solved. The utility model has advantages of simple structure and easy operation, and is suitable for on site popularization and application.
Description
Technical field:
The utility model relates to a kind of downhole tool that is used for using on the oilfield, particularly two-way nozzle hydraulic injection pump.
Background technique:
The horizontal well sand washing of shaking out is a technical problem of being badly in need of solution at present.Conventional sand washing operation is effective for straight well section and little gradient well section.Horizontal well shaft bottom sand setting must be deposited on net horizontal section, and for high angle hole section and net horizontal section sand washing, existing conventional sand washing mode belongs to band and presses sand washing, exist sand cleaning fluid to recharge the problem on stratum, sand cleaning fluid can't return ground when serious, and especially horizontal well thermal recovery damages oil reservoir.
Summary of the invention:
The purpose of this utility model is to provide two-way nozzle hydraulic injection pump, utilize negative pressure sand washing technology to adopt concentric double pipe sand washing tubing string, the anti-circulation hydraulic jet pump of the supporting two-way nozzle in down-hole, the supporting continuous cycle of higher pressure device in ground, realize the sand washing of horizontal well negative pressure, solved horizontal well high angle hole section and net horizontal section sand washing problem.
The utility model is made up of diffusing tube, trunnion, formation fluid inlet, driving nozzle, power fluid runner, outer working tube, immersible pump, sand washing nozzle, in outer working tube, there is diffusing tube to be connected with trunnion, the nozzle of driving, immersible pump, sand washing nozzle are arranged at the trunnion bottom, the formation fluid inlet is arranged, dynamic liquid runner in it on outer working tube.
The utility model is owing to adopt two-way nozzle, sand washing nozzle and driving nozzle, after power fluid is descended by two-tube annular space input well, enter Pump Suction Nozzle by the power fluid runner, be divided into two-part afterwards: a part sprays with the flow velocity forward more than the 100m/s through the sand washing nozzle, jet is fan-shaped diffusion in pit shaft, make the horizontal segment sand setting fully be suspended in the sand cleaning fluid; Another part drives the Downhole jetting pump work through driving nozzle, height contains the sand formation fluid and enters the pump work chamber by the formation fluid inlet, mix after trunnion is discharged to diffusing tube with the power fluid that drives the nozzle ejection, so just high sand-laden fluid is discharged pit shaft, and form negative pressure in the shaft bottom.Realize the sand washing of horizontal well negative pressure, solved horizontal well high angle hole section and net horizontal section sand washing problem.It is simple in structure, and is easy to use, is well suited for field popularization application.
Description of drawings:
Accompanying drawing is a structural representation of the present utility model.
Embodiment:
As shown in the figure, the utility model is made up of diffusing tube 1, trunnion 2, formation fluid inlet 3, driving nozzle 4, power fluid runner 5, outer working tube 6, immersible pump 7, sand washing nozzle 8, in outer working tube 6, there is diffusing tube 1 to be connected with trunnion 2, the nozzle 4 of driving, immersible pump 7, sand washing nozzle 8 are arranged at trunnion 2 bottoms, formation fluid inlet 3 is arranged, dynamic liquid runner 5 in it on outer working tube 6.
If two-way nozzle, sand washing nozzle 8 and driving nozzle 4, after power fluid is descended by two-tube annular space input well, enter Pump Suction Nozzle by power fluid runner 5, be divided into two-part afterwards: a part sprays with the flow velocity forward more than the 100m/s through sand washing nozzle 8, jet is fan-shaped diffusion in pit shaft, make the horizontal segment sand setting fully be suspended in the sand cleaning fluid; Another part drives the Downhole jetting pump work through driving nozzle 4, height contains the sand formation fluid and enters the pump work chamber by formation fluid inlet 3, mix after trunnion 2 is discharged to diffusing tube 1 with the power fluid that drives nozzle 4 ejections, so just high sand-laden fluid is discharged pit shaft, and form negative pressure in the shaft bottom.Realize the sand washing of horizontal well negative pressure, solved horizontal well high angle hole section and net horizontal section sand washing problem.
