Technical field
The present invention relates to a kind of liquid pumping, supercharging equipment, be specially a kind of hydraulic drive type oil pumping suction booster that is applied to petroleum industry.
Background technique
Oil field oil recovery at present adopts the mode of pumping unit-sucker rod-oil well pump combination to realize usually, and promptly sucker rod upper end connection pumping unit, lower end connect the piston of oil well pump, through carrying or transfer sucker rod on the pumping unit, realize the reciprocal reciprocating oil pumping of oil well pump; But oil reservoir is darker gradually at present; Therefore the length of sucker rod is up to two or three km, and all there is certain inclination in oil well, in sucker rod to-and-fro motion process, causes the wearing and tearing of sucker rod and oil pipe easily; Cause device damage very fast, the efficient of oil pumping system is also lower.
Summary of the invention
To the defective that existing technology exists, the object of the invention provides the hydraulic drive type oil pumping suction booster of a kind of pumping efficiency height, applied range, and can save sucker rod, has both saved equipment investment, can avoid the wearing and tearing of sucker rod and oil pipe again,
The present invention realizes through following technological scheme: comprise at least one hydraulic drive type oil pumping compress cell, hydraulic drive type oil pumping compress cell comprises that the pump that connects successively and be communicated with sucks end, first pump barrel, connecting section, second pump barrel and pump discharge end; Be respectively equipped with first plunger and second plunger that are slidingly matched in described first pump barrel and second pump barrel, and first plunger and second plunger on be equipped with passage and be connected through the hollow pull rod that runs through connecting section, be equipped with check valve assembly in the described passage; Described connecting section is provided with the hydraulic oil that is communicated with first pump barrel and second pump barrel respectively and imports and exports; Be respectively equipped with check valve assembly on the connecting passage of described pump suction end and first pump barrel, pump discharge end and second pump barrel.
Working principle of the present invention is following:
1, be used for down-hole oil production: the high voltage power liquid that ground hydraulic station is produced with the high-pressure and hydraulic oil pipe flows to the oil pumping suction booster of down-hole, drives first, second plunger work of oil pumping suction booster respectively according to time sequencing, realizes the lifting of well liquid.
2, be used for pressurized water injection: can the oil pumping suction booster be connected on water injecting pipeline, can realize the pressure relay, just can utilize the pressure of import, the boost in pressure in the waterflood-transmission line is arrived required pressure.The liquid that comes that has certain pressure acts on first plunger, and the first plunger pushing drawing rod passes to second plunger with thrust, and second pump barrel only need provide the power of supercharging part just can realize the supercharging relay.
Such scheme can also further be improved to:
Be provided with black box between described hollow pull rod and the connecting section, and fastening through the locking screw cover, prevent that the hydraulic oil in two pump barrels from scurrying mutually.Described black box comprises the seal ring at pull bar stuffing box gland and two ends thereof.
Described check valve assembly comprises valve body and interior valve ball, valve seat thereof, and two ends of valve body is provided with gasket seal.
Rational in infrastructure, the long service life of the present invention need not connect sucker rod and can accomplish the oil pumping operation, can be applied to well recovery, ground pressurized water injection, and flow process is injected in the liquid pumping of other industry, supercharging.
