Abstract
The invention relates to a hydraulic-drive plunger oil well pump which can be driven by ground power liquid or an underground hydraulic pump. A reversing device for controlling the reciprocating motion comprises a valve base, a hollow valve body, valve seats, a valve ball, a poking rod and a sliding rod. One end of the sliding rod is arranged in the hollow valve body, and an annular channel is formed between the sliding rod and an inner hole of the valve body. The reversing device acts initially by the aid of the sliding rod and is pushed to a reversing position by hydraulic pressure, and a liquid flow channel is closed and opened to enable a plunger to change the moving direction; due to the adoption of a cone valve and ball valve combined structure, the reversing device can perform reversing stably under a low-stroke operation condition, the abrasion of moving parts is low, and the service life of the pump is multiplied; the valve seat and the valve body are in linear sealing, so that leakage is avoided during working.
Description
Affiliated technical field:
The present invention relates to hydraulic drive plunger oil-well pump, relate in particular to the reciprocating reversing arrangement of a kind of control hydraulic drive plunger oil-well pump.
Background technique:
Hydraulic piston pump is by surface pump, to underwell pump, to inject high voltage power liquid to control power end piston up-down by hydraulic efficiency slide valve, thereby drives oil pump piston to move reciprocatingly, and down-hole liquid is lifted to ground.Because it adopts hydraulic pressure direct-drive, belong to rodless pump series, the exploitation of the most applicable inclined shaft and horizontal well, not only efficiency is high for it, and lift is large, also can utilize high temperature power fluid to keep temperature in wellbore to solve viscous crude, high solidifying oil flow problem.But because adopting the reciprocating reversing of Valve with sliding bush control piston, hydraulic piston pump cause hydraulic piston pump to have following shortcoming and defect: one, require power fluid to have good lubricity, sliding sleeve selector valve cannot be realized low jig frequency commutation (specified jig frequency is 58 beats/min) needs power fluid greasy property good in order to reduce the rate of wear of movement parts.Two, require power fluid to have good turbidity test, the matching gap of sliding sleeve selector valve is very accurate, and stuck for anti-anti-skid sheath, power fluid must carry out fine filtering.Three, require power fluid to have suitable viscosity, if Valve with sliding bush is Spielpassung, use water as not only movement parts quick abrasion of power fluid, the leakage of Valve with sliding bush also can be very serious.The hydraulic piston pump that last century, domestic each oil field was used is all to cook power fluid with crude oil, namely by the dehydration of Produced Liquid process, fine filtering, after heating, as power fluid, use, because the workload of floor treatment power fluid is too large, cost of production is too high, to the last century Mo whole nation, do not used hydraulic piston pump (to refer to < < oil drilling technology > the 33rd volume fifth phase of > as the oil well of artificial lift, the domestic hydraulic piston pump applied analysis of the < < > > of in September, 2011 publication).
