Abstract
The invention relates to a low-energy consumption hydraulic oil pump which comprises a pump cylinder with three sealing surfaces. A plunger piston with three sealing surfaces is matched with the pump cylinder when in use; after the pump cylinder is combined with the plunger piston, upper and lower independent annular cavities are formed between the pump cylinder and the plunger piston; a drive port is arranged in the wall of the pump cylinder and is externally connected with a drive tube; a return port is simultaneously arranged in the wall of the pump cylinder and is externally connected with a return pipe; and the drive port and the return port are respectively positioned in the upper and the lower annular cavities between the pump cylinder and the plunger piston. A traveling valve is arranged inside the plunger piston; the upper end of the pump cylinder is connected with an oil pipe; and the lower end of the pump cylinder is connected with a fixed valve. The low-energy consumption hydraulic oil pump has the beneficial effect that when raw oil is lifted, only kinetic energy for lifting the self weight of raw oil mixed liquor is required to be provided, so that the energy consumption is low.
Description
Technical field
The present invention relates to a kind of oil field and use oil well pump, especially relate to a kind of low consumption hydraulic well pump.
Background technique
At present, known oil well pump working principle pumps for adopting the ground pumping unit to provide, and pumping through sucker rod drive plunger is pumped into ground with crude oil; This kind mechanical oil recovery method need be carried out counterweight to pumping unit; Coming the weight of lower sucker rod post evenly, is example with 2000 meters following pump degree of depth oil wells, and its rod weight is near 4 tons; And only about 1.5 tons of the oil column weight of institute's pumping, fluid weight accounts for the ratio less than 30% of pumping unit total load.Working efficiency is low, wastes a large amount of electric energy.
Summary of the invention
In order to solve in the low deficiency of existing technology energy utilized rate, the present invention provides a kind of low consumption hydraulic well pump.
The technical solution adopted for the present invention to solve the technical problems is:
A kind of low energy consumption hydraulic oil well pump comprises the pump barrel that has 3 place's sealing surfaces, and what be mated use is the plunger that has 3 place's sealing surfaces; Form upper and lower two toroidal cavities independently between combination back pump barrel and the plunger; The pump barrel wall is provided with and drives mouth, drives a mouthful external driving tube, also is provided with the return mouth on the pump barrel wall simultaneously; The external return pipe of return mouth drives mouthful and the return mouth is provided with the position and lays respectively at bottom and the toroidal cavity on top between pump barrel and the plunger.Plunger inside is provided with traveling valve, and pump barrel upper end connects oil pipe, the pump barrel lower end valve that is connected and fixed.
Further specify:
During oil recovery, from driving the toroidal cavity that mouth is pressed into pump barrel and plunger bottom, under pressure, it is up to promote plunger through driving tube for driving liquid; This moment, traveling valve cut out, and standing valve is opened simultaneously, and the crude oil mixed liquor of plunger top is carried earthward through the oil pipe endoporus by the plunger lifting; Space below the plunger is filled up by crude oil mixed liquor, when plunger runs to the upper end limit position, drives the mouth pressure drain charge, then pressurizes to the toroidal cavity of pump barrel and plunger upper part through return pipe and return mouth; Under pressure, plunger is descending when a little, and traveling valve is opened; Standing valve cuts out simultaneously, and the crude oil mixed liquor of plunger top keeps original position, and the crude oil mixed liquor of plunger below is then transferred to the plunger top; For the lifting that makes progress is prepared next time, when plunger goes downwards to limit position, the drain charge of return mouth pressure; Drive mouth pressurization once more, so repeatedly, constantly crude oil mixed liquor is given rise to ground.
The invention has the beneficial effects as follows:
On the weight of lifting crude oil mixed liquor own only need be provided when carrying crude oil kinetic energy just can, it is low to consume energy.
Description of drawings

1. pump barrels among the figure, 2. plunger 3. drives mouth, 4. driving tube, 5. return mouth, 6. return pipe, 7. traveling valve, 8. oil pipe, 9. standing valve.
Embodiment
Below in conjunction with accompanying drawing and embodiment the present invention is further specified.
As shown in Figure 1, the present invention includes the pump barrel 1 that has 3 place's sealing surfaces, what be mated use is the plunger 2 that has 3 place's sealing surfaces; Form upper and lower two toroidal cavities independently between combination back pump barrel 1 and the plunger 2; Pump barrel 1 wall is provided with and drives mouth 3, drives mouthful 3 external driving tubes 4, also is provided with return mouth 5 on pump barrel wall 1 wall simultaneously; Return mouth 5 external return pipes 6, drive mouthfuls 3 and return mouth 5 position be set lay respectively at bottom and the toroidal cavity on top between pump barrel 1 and the plunger 2.Plunger 2 inside are provided with traveling valve 7, and pump barrel 1 upper end connects oil pipe 8, the pump barrel 1 lower end valve 9 that is connected and fixed.
Further specify: during oil recovery, from driving the toroidal cavity that mouth 3 is pressed into pump barrel 1 and plunger 2 bottoms, under pressure, it is up to promote plunger 2 through driving tube 4 for driving liquid; This moment, traveling valve 7 cut out, and standing valve 9 is opened simultaneously, and the crude oil mixed liquor of plunger 2 tops is carried earthward through oil pipe 8 endoporus by plunger 2 liftings; Space below the plunger 2 is filled up by crude oil mixed liquor, when plunger 2 runs to the upper end limit position, drives mouthful 3 pressure drain charges, then through return pipe 6 and the toroidal cavity pressurization of return mouth 5 to pump barrel 1 and plunger 2 tops; Under pressure, plunger 2 is descending when a little, and traveling valve 7 is opened; Standing valve 9 cuts out simultaneously, and the crude oil mixed liquor of plunger 2 tops keeps original position, and the crude oil mixed liquor of plunger 2 belows is then transferred to plunger 2 tops; For the lifting that makes progress is prepared next time, when plunger 2 goes downwards to limit position, the 5 pressure drain charges of return mouth; Drive mouthful 3 pressurizations once more, so repeatedly, constantly crude oil mixed liquor is given rise to ground.
