Description
Technical field
The utility model relates to a kind of oil well pump that recovers the oil and use, specifically a kind of novel plunger oil-well pump of well-flushing simultaneously.
Background technique
Traditional oil well pump mainly is made up of pump barrel, plunger, standing valve assembly, and plunger is positioned at pump barrel, and the standing valve assembly is positioned at the below of pump barrel.The standing valve assembly is made up of the standing valve ball cover in standing valve housing, the standing valve housing, the standing valve ball in the ball cover, the standing valve ball seat of ball cover bottom.Standing valve housing upper end is threaded with pump barrel, and its lower end is connected with joint screw thread.The standing valve ball cover is threaded with the 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 the production process, oil well pump is under the effect of ground power, move up and down in pump barrel by being connected the sucker rod upper plug: during upstroke, plunger is up, and the travelling valve in the plunger is closed, and the pump barrel internal pressure descends, when the pump barrel internal pressure is lower than the oil well pump inlet pressure, the standing valve ball is opened, and liquid and is discharged part well liquid outside well from tubing string in the pit shaft inflow pump; During down stroke, plunger is descending, and the pump barrel internal pressure raises, and the travelling valve in the plunger is opened, and the standing valve ball is closed, and the well liquid in the pump barrel is discharged in the oil pipe that reaches the plunger top in the plunger by travelling valve, and gives rise to outside the well.So move in circles, reach the purpose of extracting oil from the stratum.
The shortcoming that conventional fixed valve assembly exists is: when upstroke, when entering the pump housing, well liquid can directly produce impact force upwards, make between standing valve ball and the standing valve ball cover and produce intense impact, cause breaking and damaging of standing valve ball cover and standing valve ball easily; When down stroke, also can produce intense impact between standing valve ball and the standing valve ball seat, cause breaking and damaging of standing valve ball seat and standing valve ball easily.Therefore, there is the shortcoming that working life is short, maintenance load is big in conventional fixed valve assembly; Simultaneously, during down stroke,, cause and close the oil inlet hole hysteresis, reduced the working efficiency of oil well pump because the falling of standing valve ball distance is longer.
In addition, in installation exercise,, often stop up in the well, cause standing valve to get only the repetition operation because of not opening because of foreign material drop with oil well pump, when the standing valve assembly is lowered to oil well together.
Moreover, during clean-out service, need earlier flow string and down-hole part all to be tripped out, be lowered to normally well-flushing of Flushing tubular column again, after well-flushing is finished, Flushing tubular column all need be tripped out from pit shaft, being lowered to flow string separately can produce.Operation is numerous and diverse, and human and material resources, financial resources consumption are big, influence manufacturing efficiency, and unrestrained well liquid to ground has caused environmental pollution.
The model utility content
The purpose of this utility model is, overcomes the deficiency that existing oil well pump exists, and provides a kind of and can carry out clean-out service simultaneously, improves pump efficiency, prevents from effectively to stop up and can prolong the standing valve assembly novel standing valve assembly in working life greatly.
The utility model is achieved in that
The standing valve assembly of the utility model, form by 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 ends are threaded with upper connection 8, the lower end is threaded with lower contact 16, and standing valve ball seat 14 is fixed in its bottom.It is characterized in that: the oil outlet on the standing valve ball cover 10 is positioned at the bottom (described " bottom " means less than half height of standing valve ball cover) of standing valve ball cover 10; Ball cover card platform 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 a leg shape jump ring 13, to card key 19, standing valve ball 12 entered in the standing valve ball cover 10 by leg shape jump ring 13 in the lower end of leg shape jump ring had; On standing valve ball seat 14 walls annular groove 21 is arranged; The top of standing valve housing 15 is provided with the axial circular hole of standing valve ball cover 10 turnover, and the axial oil outlet 9 of a circle is arranged around the circular hole; 20 places, screwed connection hole of the corresponding standing valve ball cover of plunger base fixedly connected the upper end of connecting-and-unconnecting device, can in operation, finish disconnected other device that takes off or connect and connect.
Oil outlet on the said standing valve ball cover 10 is positioned at the bottom of valve ball cover 10, and its structure also can be: standing valve ball cover 10 lower sides are provided with a plurality of radial flow path hole 22; The standing valve housing 15 of standing valve cover 10 tops 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 beneficial effects of the utility model are:
1. during operation, the standing valve ball does not need to be lowered to desired location in the pit shaft with pump barrel.Be communicated with the position because pump barrel, tubing string, pit shaft are in, fall into the foreign material of tubing string like this and can be directly enter in the pit shaft, prevented the generation of obstruction from the oil inlet hole of pump barrel bottom standing valve ball seat.
2. after the shaft orientation flowing channel on the conventional fixed valve ball cover being changed into the radial flow path of ball cover middle part or bottom, the oil stream of subterranean wells liquid radially flows out between the leg shape jump ring 13 of standing valve ball cover bottom: when entering upstroke, the standing valve ball only is raised to the required minimum constructive height of oil circulation row and gets final product, and can not produce the bump with the standing valve ball cover; When entering down stroke, standing valve ball in the standing valve assembly falls from eminence, because standing valve ball fixed distance valve ball seat is lower, so the bump to the standing valve ball seat alleviates, and it is more quick to close standing valve, so not only improve the working life of standing valve assembly greatly, also improved the working efficiency of oil well pump.
3. for the oil well of producing, during as the need clean-out service, only need plunger is put to the bottom, be connected with screwed connection hole 20 on the standing valve ball cover with connecting-and-unconnecting device 7, directly mention and leave the pump barrel certain altitude, open standing valve simultaneously and can carry out operation, and need not sucker rod in the pit shaft and tubing string are tripped out pit shaft and be lowered to Flushing tubular column in addition.
