Abstract
A movable oil well casing gas recycling device comprises an oil nozzle sleeve (4), an emptying valve (5), a pressure reduction valve (6), a flowmeter (7), a pressure gauge (8) and a high-pressure hose (9). A movable oil well casing gas recycling device body is a 'cross'-shaped structure, the lower end of the movable oil well casing gas recycling device body is connected with an outlet of the oil nozzle sleeve (4), an oil nozzle is mounted in the oil nozzle sleeve (4), an inlet of the oil nozzle sleeve (4) is connected with a casing gate (3), the emptying valve (5) is mounted at the left end of the movable oil well casing gas recycling device body, the pressure gauge (8) is mounted at the right end of the movable oil well casing gas recycling device body, the pressure reduction valve (6) and the flowmeter (7) are successively mounted at the upper end of movable oil well casing gas recycling device body, and an outlet of the flowmeter (7) is connected with a sampling valve (10) via the high-pressure hose (9). The movable oil well casing gas recycling device is simple in structure and convenient to operate, is safe and reliable, and reduces labor intensity of staff. Oil well casing gas can be recycled movably, high-pressure natural gas can be changed into low-pressure natural gas which is recycled to an oil collecting trunk line, the problem that natural gas pollutes environments is stopped, oil well casing pressure is reduced, 'pumping efficiency' of a deep-well pump is improved, and yield of a crude oil is increased.
Description
Technical field
the utility model relates to oil field well casing natural gas recovery technology, specifically is a kind of movable well casing gas recovery device.
Background technology
In
oil well production process; When bottom pressure is reduced to when being lower than saturation pressure, natural gas is just separated from crude oil, and an isolated natural gas part accumulates in oil sets annular space; Form in " sleeve pipe gas "; Force well fluid level to descend, the effective producing pressure differential of oil well is reduced, production capacity descends; A part gets into the oil well pump pump chamber with flow, occupies certain pump chamber space, influence pump efficiency, in the time of seriously " gas lock " can take place, and makes the deep well pump can't ordinary production.And coagulate oilfield for height, average moisture 60%, part oil well paraffinication is serious; Oil well need regularly carry out the high-pressure boiler hot clean-up well; Because it is low that heat is washed the pressure of equipment ability, all need the sleeve pipe atmospheric pressure be reduced to below the 1Mpa before all each heat are washed, and can carry out heat and wash work.In order to keep the ordinary production of oil well; To the too high oil well of casing pressure with regularly need the oil well of hot-washing wax remover, need carry out emptying to sleeve pipe gas, so not only environment has been caused pollution; And the waste natural gas resource, also exist the serious potential safety hazard of easy breaking out of fire.
Summary of the invention
The purpose of
the utility model is exactly the technological deficiency to above-mentioned existence, designs a kind of movable well casing gas recovery device.
The purpose of the utility model is realized by following technical proposals:
the utility model comprises: oil nozzle cover, emptying valve, pressure loading valve, flow meter, pressure meter, high-pressure hose.Its movable well casing gas recovery device is " ten " font structure, and the lower end connects with the outlet of oil nozzle cover, in the oil nozzle cover oil nozzle is housed; The oil nozzle diameter is selected as required; The import of oil nozzle cover connects with sleeve gate, and left end is equipped with the emptying valve, and right-hand member is equipped with pressure meter; The upper end is equipped with pressure loading valve, flow meter successively, and the flow meter outlet connects with sample cock through high-pressure hose.
The beneficial effect of
the utility model is: this apparatus structure is simple, easy to operate, safe and reliable, alleviates personnel labor.The sleeve pipe gas of removable all oil wells of recovery becomes low pressure natural gas with high-pressure natural gas and is recycled to the oil-collecting main line, has stopped the destruction of natural gas to earth environment, has reduced the oil well casing pressure, improves " pump efficiency " of deep well pump, increases crude output.
Description of drawings
accompanying drawing is that the utility model is used the main broken section structural representation of looking.
In
accompanying drawing, 1. production tree 2. produces gate, 3. sleeve gate, 4. oil nozzle cover, 5. emptying valve, 6. pressure loading valve, 7. flow meter, 8. pressure meter, 9. high-pressure hose, 10. sample cock, 11. back pressure valves.
The specific embodiment
Below in conjunction with accompanying drawing further elaboration is done in the enforcement of the utility model:
the utility model is made up of oil nozzle cover 4, emptying valve 5, pressure loading valve 6, flow meter 7, pressure meter 8, high-pressure hose 9.Its movable well casing gas recovery device is " ten " font structure; The lower end connects with 4 outlets of oil nozzle cover, in the oil nozzle cover 4 oil nozzle is housed, and oil nozzle overlaps 4 imports and connects with sleeve gate 3; Left end is equipped with emptying valve 5; Right-hand member is equipped with pressure meter 8, and the upper end is equipped with pressure loading valve 6, flow meter 7 successively, and flow meter 7 outlets connect with sample cock 10 through high-pressure hose 9.
Claims (1)
