Description
Technical field
The present invention relates to a kind of oil well pump used that recovers the oil, specifically a kind of can the Novel plunger oil well pump of simultaneously well-flushing.
Background technique
Traditional oil well pump, primarily of pump barrel, plunger, standing valve assembly composition, plunger is positioned at pump barrel, and standing valve assembly is positioned at the below of pump barrel.Standing valve assembly is made up of the standing valve ball seat bottom the standing valve ball cover in standing valve housing, standing valve housing, the standing valve ball in ball cover, ball cover.Standing valve housing upper end is threaded with pump barrel, and its lower end is connected with joint screw thread.Standing valve ball cover is threaded with standing valve ball seat, and there is well liquid oil inlet hole at the center of standing valve ball seat, and well liquid oil outlet is arranged at the top of standing valve ball cover.
In production process, oil well pump is under the effect of Surface power drive, move up and down in pump barrel by being connected to sucker rod upper plug: during upstroke, plunger is up, and the travelling valve in plunger is closed, and pump barrel internal pressure declines, when pump barrel internal pressure is lower than oil well pump inlet pressure, standing valve ball is opened, liquid from pit shaft inflow pump, and to discharge section well liquid outside well from tubing string; During down stroke, plunger is descending, and pump barrel internal pressure raises, and the travelling valve in plunger is opened, and standing valve ball is closed, and the well liquid in pump barrel is discharged in the oil pipe in plunger and above plunger by travelling valve, and gives rise to outside well.So move in circles, reach the object extracting oil from stratum.
The shortcoming that tradition standing valve assembly exists is: when upstroke, well liquid directly can produce impact force upwards when entering the pump housing, make to produce intense impact between standing valve ball and standing valve ball cover, easily cause breaking and damaging of standing valve ball cover and standing valve ball; When down stroke, between standing valve ball and standing valve ball seat, also can produce intense impact, easily cause breaking and damaging of standing valve ball seat and standing valve ball.Therefore, there is the shortcoming that working life is short, maintenance load is large in traditional standing valve assembly; Meanwhile, during down stroke, because the falling distance of standing valve ball is longer, cause closedown oil inlet hole delayed, reduce the working efficiency of oil well pump.
In addition, in installation exercise, when removing oil well pump, standing valve assembly one into oil well, often because foreign material drop in well and block, standing valve is caused to get only repetition operation because not opening.
Moreover, during clean-out service, need first flow string and underground part are all tripped out, then under enter Flushing tubular column can normal well-flushing, after well-flushing completes, need Flushing tubular column all to trip out from pit shaft, entering down flow string separately can produce.Operation is numerous and diverse, and human and material resources, financial resources consumption are large, affect manufacturing efficiency, and spills the well liquid fallen earthward and cause environmental pollution.
Summary of the invention
The object of the invention is to, overcome the deficiency that existing oil well pump exists, provide one can carry out clean-out service simultaneously, improve pump efficiency, effectively prevent blocking and the Novel fixed valve assembly that greatly can extend standing valve assembly working life.
The present invention is achieved in that
The standing valve assembly of the present invention, be made up of standing valve housing 15, standing valve ball cover 10, standing valve ball 12, standing valve ball seat 14, upper connection 8, lower contact 16, standing valve housing 15 upper end is threaded with upper connection 8, lower end is threaded with lower contact 16, and is fixed bottom it by standing valve ball seat 14.It is characterized in that: the oil outlet on standing valve ball cover 10 is positioned at the bottom (described " bottom ", means the height being less than standing valve ball cover half) of standing valve ball cover 10; Ball cover chuck 18 is arranged at the top of standing valve ball cover 10, its top center place is provided with screwed connection hole 20, in order to be connected with lower half portion of connecting-and-unconnecting device, its underpart is leg shape jump ring 13, the lower end of leg shape jump ring has interior to card key 19, and standing valve ball 12 enters in standing valve ball cover 10 by leg shape jump ring 13; Annular groove 21 is arranged at the top of standing valve ball seat 14 wall; The top of standing valve housing 15 is provided with the axial circular hole of standing valve ball cover 10 turnover, and there is a circle Axial-running Out oilhole 9 in the surrounding of circular hole; Screwed connection hole 20 place of the corresponding standing valve ball cover of plunger base is fixedly connected the upper end of connecting-and-unconnecting device, can complete disconnected other device that is de-or that connect and connect in operation.
Oil outlet on said standing valve ball cover 10 is positioned at the bottom of valve ball cover 10, and standing valve ball cover 10 lower sides is provided with multiple radial flow path hole 22; Standing valve housing 15 above standing valve cover 10 is provided with card seal apparatus 24, and this card seal apparatus can be jump ring or spring sheet, upper plug head, movable pin, rubber ring.
The invention has the beneficial effects as follows:
1., during operation, standing valve ball need with the desired location in pump barrel lower going-into-well cylinder.Because pump barrel, tubing string, pit shaft are in and are communicated with position, the foreign material falling into tubing string like this can directly enter in pit shaft from the oil inlet hole of pump barrel bottom standing valve ball seat, prevent the generation of blocking.
2. the shaft orientation flowing channel on traditional standing valve ball cover is changed in the middle part of ball cover or bottom radial flow path after, the oil stream of subterranean wells liquid flows out from radial between the leg shape jump ring 13 of standing valve ball cover bottom: when entering upstroke, standing valve ball is only raised to the required minimum constructive height of oil circulation row, can not produce the shock with standing valve ball cover; When entering down stroke, standing valve ball in standing valve assembly falls from eminence, because standing valve ball distance standing valve ball seat is lower, therefore the shock of standing valve ball seat is alleviated, and closedown standing valve is more quick, so not only substantially increase the working life of standing valve assembly, also improve the working efficiency of oil well pump.
3. for the oil well produced, during as needed clean-out service, only need plunger be put to bottom, be connected with the screwed connection hole 20 on standing valve ball cover with connecting-and-unconnecting device 7, directly mention and leave pump barrel certain altitude, open standing valve simultaneously and can carry out operation, and without the need to the sucker rod in pit shaft and tubing string are tripped out pit shaft and in addition under enter Flushing tubular column.
