Abstract
The utility model discloses an oil-drainable tube type oil-well pump, which is suitable for an oil exploitation well. The pump consists of a pump cylinder assembly (1), a plunger piston assembly (3) and a standing valve assembly (14), wherein two clamping jaws (8) are arranged at the lower end of a lower joint (7) of a plunger piston; a groove (9) is arranged in the upper end of a standing valve cover (10); the clamping jaws (8) are matched with the groove (9); two oil outlets are arranged in the groove (9), and a valve rod (12) and a spring (11) are mounted in one oil outlet; an ejector rod (5) is mounted in a center position of the upper end of the standing valve cover (10); when oil needs to be drained, the two clamping jaws (8) enter the groove (9) in the standing valve cover (10), and push the compression spring (11) of the valve rod (12) to move downwards, a standing valve ball (11) is poked away by the valve rod (12), a floating valve ball (14) is ejected away by the ejector rod (5), and crude oil in an oil tube on the pump is drained into the well. The problem of oil drainage during well remedial work is solved, and the crude oil is prevented from polluting the environment.
Description
Technical field
But the utility model relates to a kind of draining tubing pump, and it is applicable to the petroleum production oil well.
Background technique
General tubing pump can not draining, and liquid can not enter in the well in the oil pipe when workover eration plays oil pipe, can overflow ground, and befouling environment is unfavorable for civilized construction.Will oil drainer be installed at tubing pump, when oil well pump worked, oil drainer was in closed condition for this reason, when the needs workover eration, then opened oil drainer, discharged the liquid in the oil pipe.At present, the oil drainer kind of field by using is a lot, and structure is different, operates different, generally all be to be connected with oil well pump by tubing round thread, after oil pump plunger piston tripped out, drop into again opening device oil drainer is opened to realize draining, like this, not only operation is inconvenient, and many one reconnect many one risks, and a lot of oil drainers misoperation automatic leakage when oil well pump work is oily, causes and can't pump.
Summary of the invention
But the purpose of this utility model provides a kind of tubing pump of draining, can directly the crude oil in the oil pipe on the pump be let out in the stratum when needing, and is safe and reliable, and the draining problem when efficiently solving workover eration avoids crude oil to overflow the ground pollution environment.
The utility model is comprised of pump barrel assembly, plunger piston assembly, standing valve assembly, the plunger lower contact lower end of its plunger piston assembly is provided with two claws, uniform a plurality of oil outlets on the standing valve cover of standing valve assembly, the upper end of standing valve cover has a groove, two claws of plunger lower contact match with groove, two oil outlets are arranged in the groove, valve rod and spring are housed in one of them oil outlet, a push rod is equipped with in central position, standing valve cover upper end.When underground work needs draining, it is descending that sucker rod drives plunger piston assembly, when the claw that comes downwards to the plunger lower contact touches the standing valve cover upper-end surface of standing valve assembly, rotary sucker rod, two claws of plunger lower contact are entered in the groove of standing valve cover upper end, it is descending that the claw of plunger lower contact promotes the valve rod Compress Spring, valve rod is pushed fixed valve ball aside, make fixed valve ball depart from fixed valve base, the push rod of standing valve cover upper end backs down the valve ball that moves about of plunger piston assembly at this moment, crude oil on the pump in the oil pipe is by the endoporus of plunger piston assembly and the endoporus of the valve seat that moves about, oil outlet and fixed valve base by standing valve cover enters in the well again, draining problem when efficiently solving workover eration avoids crude oil to overflow ground, befouling environment.
The utility model reasonable and compact in structure can realize the direct draining of oil well pump, and is safe and reliable.
