Abstract
The utility model relates to a downhole tool, especially two-way nozzle hydraulic jet pump that is used for oil field oil well to go up to use. The utility model is composed of a diffusion pipe, a choke, a stratum fluid inlet, a driving nozzle, a power fluid flow channel, an external working barrel, a sinking pump and a sand washing nozzle, the utility model adopts a bidirectional nozzle, the sand washing nozzle and the driving nozzle, the power fluid enters the suction inlet of the pump through the power fluid flow channel after being input into the well from a double-pipe annular space, one part of the power fluid is positively ejected out through the sand washing nozzle at the flow speed of more than 100m/s, and the jet flow is diffused in a fan shape in a shaft, so that the settled sand in the horizontal section is fully suspended in the sand washing fluid; the other part drives the underground jet pump to work through the driving nozzle, is mixed with power liquid sprayed out of the driving nozzle and then is discharged from the venturi tube to the diffusion tube, negative pressure is formed at the bottom of the well, negative pressure sand washing of the horizontal well is achieved, and the problem of sand washing of a highly-deviated well section and a horizontal well section of the horizontal well is solved. The device has simple structure and convenient use, and is very 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.
