Abstract
This invention is high efficiency reverse oil-well pump. It includes oil pipe, barrel, sucker rod, trunk piston, upper traveling valve, lower traveling valve and bottom valve. The upside of trunk piston connects to drag link, the upside of which is set with upper traveling valve. The sucker rod and upper traveling valve connect to drive the drag link. The underside of trunk piston connects to lower traveling valve. The corresponding drag link and trunk piston are respectively arranged with seal ring components device. The oil trunk is separated above drag link. Thus, the trunk piston discharges oil when under down stroke, so that it reversely pumps oil.
Description
Technical field
What the present invention relates to is oilfield oil recovery oil well pump.
Background technique
Oil well pump is the device that extracts down crude oil from oil well, and the technical requirements of oil well pump is mainly shown its sealing, sand control card, anti-wear, pump efficiency and on working life.Existing oil well pump is for pursuing above-mentioned purpose, under the constant situation of oil well pump basic principle various improvement structures arranged, and in the hope of working life and pump efficiency preferably, the difference on the various oil well pump structure constructions, characteristics and effect are different.As CN95235086,97205005,00211934,00212570,01226808,02228867,03254270,03254271, Chinese patents such as 200420030304 are disclosed is exactly this class technology.
Invent novel content
The purpose of this invention is to provide a kind of rational in infrastructurely, pump seal, sand control card, anti-wear property are good, the efficient reversed beam-pumping unit of long service life, i.e. down stroke formula oil well pump.
The present invention includes oil pipe 1, pump barrel 2, sucker rod 3, plunger 4, wander up and down valve 5,6, bottom valve 7, it is characterized in that being connected with pull bar 8 in the upper end of plunger 4, in the connection of the upper end of pull bar 8 upper travelling valve 5 is set, sucker rod 3 is connected drive pull bar 8 with upper travelling valve 5, in the connection of the lower end of plunger 4 lower travelling valve 6 is set, corresponding pull bar 8 and plunger 4 are respectively equipped with ring assembly device 9a, 9b on pump barrel body assembly, and the ring assembly device is made up of seal rack 91, seal ring 92, split circlip 93.
The present invention, its corresponding pull bar and plunger on pump barrel body assembly are respectively equipped with the ring assembly device, oil column every on pull bar top, thereby realized that plunger carries out oil extraction work when down stroke is moved, promptly form oppositely oil pumping, and it is different with the oil extraction of conventional oil well pump upstroke, that can utilize sucker rod like this finishes down stroke and oil extraction work from gravity, and just mention the oil suction of beam hanger weight during upstroke, be not subjected to the influence of well depth head of liquid, reduce pumping unit power thereby can reach, save the effect of pumping unit power consumption.It is simple and reasonable, makes easyly, and cost of production is low, pull bar and plunger are respectively equipped with compensable ring assembly device, and the anti-wear property of overall structure sealing and sand control card is good, and the sealing that guarantees pump can be arranged, have and improve pump efficiency, long service life, and be applicable to deep-well.
