Employing air pressure lifts, it it is the oil production method that in modern oil recovery process, economic benefit is best, gaslift can not be limited by oil well depth, inject gas and can the most gradually go deep in liquid by gas lift valves at different levels, liquid weight above bottom oil pipe is made to lighten, and reduce the back pressure to oil reservoir, thus ensure that oil well produces the most continuously.And existing gas lift valve is in use, spheroid is under the superpower impetus of high pressure draught, constantly move back and forth, continual mutual collision is i.e. occurred to cause the air-tightness of spheroid to decline between spheroid and ball seat, the accommodative facility of oil pipe inner fluid is declined by gas lift valve, and the efficiency ultimately resulting in gas-lift production reduces.
Summary of the invention
It is an object of the invention to provide a kind of pressure regulator, while conveniently regulating and controlling high pressure draught injects, it is ensured that air-tightness stable between oil pipe and sleeve pipe, during improving gas-lift production, regulate and control efficiency.
The purpose of the present invention is achieved through the following technical solutions:
nullA kind of pressure regulator，Including housing，Regulation chamber is offered the most successively in described housing、Inlet chamber and adapter cavity，Described regulation intracavity is provided with and is filled with compressed-air actuated air bag，And regulation chamber is connected with inlet chamber by air-vent，Successively decrease downwards along the axis of push rod in the aperture of described air-vent，At described air-vent inwall and it is axially installed with spiral protrusion along it，Described inlet chamber is connected with adapter cavity by aperture，Described adapter cavity connects with oil pipe，Intercommunicating pore is had in the both sides of described inlet chamber，And in the middle part of inlet chamber, it is provided with T-shaped push rod，Return spring is set in the vertical section of push rod，The vertical section top of push rod extends upwardly to be connected with air bag after running through air-vent，The first spheroid for sealed aperture it is provided with bottom push rod horizontal segment，And on the inwall of inlet chamber, it is additionally provided with the pad of elastomeric material，The sealing hole coaxial with aperture is had in the middle part of pad，The aperture in described sealing hole is less than the diameter of the first spheroid.For in prior art during gas-lift production, high pressure draught is regulated problem that is inaccurate and that cause oil recovery efficiency to reduce, inventor carries out coordinated signals by arranging different cavitys to high pressure draught, make high pressure draught circulation between sleeve pipe and oil pipe the most smooth, regulation is more accurate, and then improves the efficiency of gas-lift production；nullDuring use，In the sleeve pipe annular section with oil pipe, multiple housing is set，Now adapter cavity is internal with oil pipe connects，Insulated between inlet chamber and adapter cavity，And return spring is in extended state，Substantial amounts of high pressure draught is injected in sleeve pipe，High pressure draught enters into inlet chamber by intercommunicating pore and leads to，While inlet chamber is filled，High pressure draught is entered in regulation chamber by air-vent，And the air bag that the space regulating intracavity is inflated is filled，By the extruding to air bag of the high pressure draught of injection，Air bag produces deformation and makes the volume of self reduce，Now the downforce of push rod is reduced by air bag，Under the return action power of return spring，Move on push rod，Drive the first spheroid to cancel the sealing to aperture simultaneously，High pressure draught in inlet chamber then by decompressing by pinhole to enter in oil pipe quickly through transitional cavity，By the high pressure draught partial offset to oil pipe inner fluid gravity，Lift needed for fluid in oil pipe rises significantly declines，The fluid i.e. accelerated in oil pipe pumps out efficiency.
