Abstract
The utility model relates to a petroleum exploiting device, in particular to a drivepipe gas automatic recovery device. The drivepipe gas automatic recovery device is characterized by comprising a pressure adjusting switch, a compressor, a separator, a first check valve, drivepipe valves, a second check valve, and an air entering control valve. Pipelines which are connected with the drivepipe valve and the first check valve are provided with the separator and the compressor, the compressor is connected with the pressure adjusting switch, and the output end of the compressor is connected with an external transmission process through the second check valve and the air entering control valve. The drivepipe gas automatic recovery device has the advantages that one of the drivepipe valves is closed, the other drivepipe valve is connected on the natural gas compressor and the oil gas separator which are arranged in an anti-theft box through the check valves, natural gas enters the crude oil external transmission process after pressure is boosted by the compressor passing through the separator, and therefore the purpose of recovery is achieved. The drivepipe gas automatic recovery device further has the advantages of solving the problems being brought by excessively high casing pressure and environmental pollution caused by willfully discharging the drivepipe gas, achieving the purposes of saving energy and reducing emission, and acquiring good social benefits and economic benefits.
Description
Technical field
The utility model relates to a kind of oil exploration equipment, particularly a kind of sleeve pipe gas automatic recycling device.
Background technology
In the oil extraction process, Oil, Water, Gas fluid-mixing in the stratum is submitted ground by extracting device of oil, the gas that is partly dissolved in the fluid-mixing is separated into free gas gradually from crude oil, and slowly expands, and enters the annular space of oil pipe and sleeve pipe until disengaging crude oil.This part natural gas is called as sleeve pipe gas.When the pressure that produces when sleeve pipe gas is higher, will cause producing fluid level to decline to a great extent, producing pressure differential reduces, and influence pump efficiency, also can cause all kinds of oil extraction pump cavitations in the time of seriously, makes the oil well pump can't operate as normal.Cause submergence to cross low and oil well pump " gas lock " phenomenon takes place in order to prevent that casing pressure is too high, generally the method for Cai Yonging is that sleeve pipe is exitted.And cancellation sleeve pipe control valve is discharged into sleeve pipe gas in the atmosphere, has not only wasted a large amount of solution gas resources, has also caused serious atmosphere pollution.
At present, existing part oil well has been installed a kind of " the anti-theft type oil jacket is communicated with casing gas recovering device ", and by sealing a sleeve gate, another sleeve gate is connected in the production procedure through ball-and-seat linker, Tube preventing from being sawed line,, sleeve pipe gas through build the pressure greater than the pipeline back pressure laggard go into outside the flow process defeated.Because ball-and-seat is set, even casing pressure is lower than back pressure, the extraction liquid in the flow process can not flow backwards yet.Linker is protected with anti-theft box, and thimble connector, sleeve pipe plug etc. all is set to anti-theft type.
Through use after a while, this simple and easy sleeve pipe gas reclaims technology still can not in time alleviate casing pressure, because under most of situation, the sleeve pipe atmospheric pressure is lower, can't open ball-and-seat automatically, and casing pressure still has a negative impact to producing fluid level.
Summary of the invention
The purpose of this utility model is exactly the above-mentioned defective that exists at prior art, and a kind of sleeve pipe gas automatic recycling device is provided, and has solved the too high variety of issue that brings of casing pressure and sleeve pipe gas and has arbitrarily discharged the problem of environmental pollution that causes.
Its technical scheme is: comprise pressure regulating switch, compressor, eliminator, first ball-and-seat, sleeve valve, second ball-and-seat, air intake control valve door, the pipeline that is connected with sleeve valve and first ball-and-seat is provided with eliminator and compressor, compressor is connected with pressure regulating switch, and the output of compressor is connected to outer defeated flow process by second ball-and-seat and air intake control valve door.
Above-mentioned compressor and the outside of eliminator are provided with theft-proof box.
The beneficial effects of the utility model are: with one of them sleeve gate sealing, another sleeve gate is connected on the theft-proof box interior natural gas compressor and gs-oil separator through ball-and-seat, through after the natural gas via compressor boost of eliminator, enter the crude oil exporting flow process, realize the purpose that reclaims; Solve the too high variety of issue that brings of casing pressure and sleeve pipe gas and arbitrarily discharged the problem of environmental pollution that causes, realized the purpose of energy-saving and emission-reduction, obtained good social benefit and economic benefit.
Description of drawings
Accompanying drawing 1 is structural representation of the present utility model;
Among the last figure: pressure regulating switch 1, compressor 2, eliminator 3, first ball-and-seat 4, first pressure meter 5, sleeve valve 6, theft-proof box 7, second ball-and-seat 8, second pressure meter 9, air intake control valve door 10, defeated flow process 11 outward.
The specific embodiment
By reference to the accompanying drawings 1, the utility model will be further described:
The utility model comprises pressure regulating switch 1, compressor 2, eliminator 3, first ball-and-seat 4, first pressure meter 5, sleeve valve 6, theft-proof box 7, second ball-and-seat 8, second pressure meter 9, air intake control valve door 10, defeated flow process 11 outward, the pipeline that is connected with first pressure meter 5, sleeve valve 6 and first ball-and-seat 4 is provided with eliminator 3 and compressor 2, compressor 2 is connected with pressure regulating switch 1, and the output of compressor 2 is connected to outer defeated flow process 11 by second pressure meter 9, second ball-and-seat 8 and air intake control valve door 10.
Wherein, the outside of compressor 2 and eliminator 3 is provided with theft-proof box 7, can strengthen theftproof performance.
Compressor of the present utility model is controlled by pressure regulating switch, when sleeve pipe reaches 0.3MPa through building the pressure, and compressor start; When casing pressure was down to 0.1 MPa, compressor stopped action; Pressure regulating switch can arrange according to the situation of different oil wells, can recycle through the light oil that eliminator is separated.
By natural gas compressor and eliminator are installed, solved the problem that casing pressure is not enough to open ball-and-seat; By pressure control switch, realized that sleeve pipe gas reclaims automatically, will overlap pressure-controlled in the reasonable scope, both avoided the too high initiation of casing pressure " gas lock ", avoided the problem that casing pressure reduces too much, producing pressure differential is excessive, water content raises again; By the control of ball-and-seat, avoided the crude oil in the external transport pipeline to reflux; By the pressure meter before and after the compressor, can realize monitoring in real time to casing pressure.
