The invention relates to a cavity capsule type air-pressure guide pump which mainly solves the problem of complicated structure and high operation failure rate of the prior oil-well pump. The cavity capsule type air-pressure guide pump is characterized in that the middle of a pump barrel (1) is fixed with a guide pipe (2), an annular cavity (3) is arranged between the pump barrel (1) and the guide pipe (2), the upper end of the annular cavity (3) is connected with an air compressor sequentially through an air guide pipe (5) and an air inlet and outlet reversing valve, the lateral wall of the lower end of the guide pipe (2) is provided with a liquid inlet (4), the upper end of the guide pipe (2) is connected with an oil pipe (12) through a check valve (11), and the lower end of the guide pipe (2) is connected with the check valve (11). The cavity capsule type air-pressure guide pump has few movable parts and takes compressed air provided by a ground air compressor as a power source, thereby having the advantages of simple structure, low failure rate and operation cost, security and reliability.
Description
Technical field:
The present invention relates to a kind of crude oil lift device, especially cavity capsule type air-pressure guide pump in the oil recovery field, oil field.
Background technique:
In oil recovery field, oil field, oil well pump is main crude oil lift device, the working principle of existing oil well pump is to utilize plunger to-and-fro motion pumping down-hole liquid, mainly be made up of pump barrel, plunger etc., realize that the plunger to-and-fro motion needs power source and ground installation, the corollary equipment cost is higher and expend a large amount of electric energy when using, the down-hole moving element is many, complex structure, raw materials consumption is big, run time fault rate height.
Summary of the invention:
In order to solve existing oil well pump complex structure and the high problem of run time fault rate, the invention provides a kind of cavity capsule type air-pressure guide pump, this cavity capsule type air-pressure guide pump moving element is few, the pressurized air that provides by the ground air compressor is as power source, have simple in structure, rate of fault is low, operating cost low and safe and reliable characteristics.
Technological scheme of the present invention is: this cavity capsule type air-pressure guide pump comprises pump barrel, the center fixed of pump barrel has honeycomb duct, between pump barrel and the honeycomb duct annular chamber is arranged, the upper end of annular chamber links to each other with air compressor by air pipe, intake and exhaust selector valve successively, the lower end sidewall of honeycomb duct has inlet opening, the upper end of honeycomb duct connects oil pipe by one-way valve, and the lower end of honeycomb duct is connected with one-way valve.
Above-mentioned air pipe is connected with one-way valve; The pump barrel lower end links to each other by the gas-liquid separation cover of connecting tube with " U " type, and the lower end side of connecting tube has through hole, and connecting tube is fixed on the bottom of gas-liquid separation cover; Air bag is arranged in the annular chamber, and air bag communicates with air pipe.
The present invention has following beneficial effect: owing to take such scheme, the Exhaust Open of intake and exhaust selector valve, down-hole liquid is through the gas-liquid separation cover, one-way valve enters honeycomb duct, inlet opening through the honeycomb duct lower end enters in the annular chamber again, when liquid level rises to certain altitude, the one-way valve of honeycomb duct lower end is closed, the commutation of intake and exhaust selector valve, exhaust close, air inlet open, injecting compressed air in annular chamber, liquid in the annular chamber is squeezed in the honeycomb duct, one-way valve by honeycomb duct top enters oil pipe, when the liquid level of annular intracavity liquid drops near inlet opening, and the commutation of intake and exhaust selector valve, inlet close, Exhaust Open, begin feed liquor this moment, finishes a circulation.This action that moves in circles can make down-hole liquid constantly be given rise to ground, compares durable in usely, simple in structure with existing oil well pump, and rate of fault is low, and operating cost is low, and is safe and reliable.
Description of drawings:
Accompanying drawing 1 is a structure sectional view of the present invention;
Accompanying drawing 2 is another embodiment of the present invention structure sectional views.
1-pump barrel among the figure, 2-honeycomb duct, 3-annular chamber, 4-inlet opening, 5-air pipe, 6-one-way valve, 7-gas-liquid separation cover, 8-connecting tube, 9-through hole, 10-air bag, 11-one-way valve, 12-oil pipe.
Embodiment:
The invention will be further described below in conjunction with accompanying drawing:
By shown in Figure 1, this cavity capsule type air-pressure guide pump comprises pump barrel 1, the center fixed of pump barrel 1 has honeycomb duct 2, between pump barrel 1 and the honeycomb duct 2 annular chamber 3 is arranged, the upper end of annular chamber 3 links to each other with air compressor by air pipe 5, intake and exhaust selector valve successively, intake and exhaust selector valve and air compressor are placed on ground, by control air inlet of intake and exhaust selector valve and exhaust.The lower end sidewall of honeycomb duct 2 has inlet opening 4, can make the liquid in the honeycomb duct 2 enter annular chamber 3 by inlet opening 4, the upper end of honeycomb duct 2 connects oil pipe 12 by one-way valve 11, can above oil pipe 12, connect multistage one-way valve 11, the lower end of honeycomb duct 2 is connected with one-way valve 11, and down-hole liquid can enter in the honeycomb duct 2 by the one-way valve 11 of honeycomb duct 2 lower ends.
By shown in Figure 2, can be provided with air bag 10 in the annular chamber 3, air bag 10 communicates with air pipe 5, and air inlet is expanded in the air bag 10, and the liquid in the extruding annular chamber 3 enters honeycomb duct 2 by inlet opening 4, liquid is risen enter in the oil pipe 12 on honeycomb duct 2 tops.
During actual the use, the Exhaust Open of intake and exhaust selector valve, down-hole liquid is through gas-liquid separation cover 7, one-way valve 11 enters honeycomb duct 2, inlet opening 4 through honeycomb duct 2 lower ends enters in the annular chamber 3 again, when liquid level rises to certain altitude, the one-way valve 11 of honeycomb duct 2 lower ends is closed, the commutation of intake and exhaust selector valve, exhaust close, air inlet open, injecting compressed air in annular chamber 3, liquid in the annular chamber 3 is squeezed in the honeycomb duct 2, one-way valve 11 by honeycomb duct 2 tops enters oil pipe 12, when the liquid level of liquid in the annular chamber 3 drops near inlet opening 4, and the commutation of intake and exhaust selector valve, inlet close, Exhaust Open, begin feed liquor this moment, finishes a work cycle.This action that moves in circles can make down-hole liquid constantly be given rise to ground.But this cavity capsule type air-pressure guide pump plural serial stage uses, and is applied to deep well, compares durable in usely, simple in structure with existing oil well pump, and rate of fault is low, and operating cost is low, and is safe and reliable.
