Abstract
The utility model relates to an oil well casing gas recovery device, in particular to a portable oil well casing gas recovery device. The technical scheme includes that the portable oil well casing gas recovery device comprises an inlet connector, a gas liquid separator, a high pressure connection hose, a control instrument panel, a natural gas compressor, a gas flow gauge, a check valve and an outlet connector, a casing lock gate of an oil extraction wellhead is connected with the inlet of the gas liquid separator through the high pressure connection hose, the outlet of the gas liquid separator is connected onto the natural gas compressor, the control instrument panel is arranged on one side of the natural gas compressor, and the outlet of the natural gas compressor is connected with an oil gathering trunk line through the gas flow gauge, the check valve and the outlet connector. The portable oil well casing gas recovery device has the advantages that casing gas enters into the separator through the casing lock gate, natural gas which is separated to be clean enters into the natural gas compressor for compression through the high pressure connection hose, and therefore pressure of the natural gas rises to 1.7Mpa from 0.1Mpa. Accordingly, the pressurized natural gas enters into the oil gathering trunk line after being metered by the flow gauge and then is output. Furthermore, the portable oil well casing gas recovery device prevents the casing gas from being discharged into the atmosphere, and not only saves resources but also protects the environment, and additionally social benefit obtained is far greater than economic benefit.
Description
Technical field
The utility model relates to a kind of well casing gas recovery device, particularly a kind of Portable oil-well casing gas recovering device.
Background technology
During oil well production, the natural gas of association is as the energy of a kind of cleaning, efficient, high-quality, obtained both domestic and externally generally paying attention to, and for a long time, each oil field well casing gas is very general with unexpected row, the situation of producing without sleeve valve.Well casing gas enters in atmosphere, both severe contamination atmospheric environment, wasted again non-renewable natural gas resource.
At present, on-the-spot in order to reduce the discharge of natural gas, the methods such as oil jacket connection that adopt are recycled casing gas more, but because the low back pressure of casing gas pressure is too high, cannot enter oil-collecting main line, while surveying liquid level, casing gas is all to enter in atmosphere, the environment that has been severe contamination, wasted again resource, the casing gas hypertonia that some wells are suppressed has caused impact to oil well pump, in order to prevent the too high impact that oil well pump is caused of casing pressure, needs regular relief sleeve gas to reduce the impact of gas on oil well pump, casing gas just enters in atmosphere, severe contamination environment.
Summary of the invention
The purpose of this utility model is exactly in view of the foregoing defects the prior art has, a kind of Portable oil-well casing gas recovering device is provided, can guarantee the normal production of oil well pump, can, by well casing gas the automatic recovery, thoroughly solve the outer row's of well casing gas a difficult problem again.
Its technical scheme is: comprise inlet union, gas-liquid separator, high pressure connecting hose, controller dial plate, natural gas compressor, gas flowmeter, ball-and-seat, outlet connection, by high pressure connecting hose, the sleeve gate of production wellhead is connected with the import of gas-liquid separator, the outlet of gas-liquid separator is connected to natural gas compressor, controller dial plate is located at a side of natural gas compressor, and the outlet of described natural gas compressor is connected with oil-collecting main line by gas flowmeter, ball-and-seat and outlet connection.
Above-mentioned gas-liquid separator is connected to form by a separator and second separator.
The exit of above-mentioned natural gas compressor is provided with safety alarm device, and the input of natural gas compressor connects fire-proof motor.
Above-mentioned natural gas compressor adopts two-stage compressor.
The beneficial effects of the utility model are: casing gas enters eliminator through sleeve gate, separated clean natural gas enters natural gas compressor compression along high pressure connecting hose, make gas pressure by the 0.1Mpa liter of import be 1.7Mpa, thereby it is inside and outside defeated to make to enter oil-collecting main line after the natural gas via flow meter metering after supercharging; And this device stopped casing gas and entered atmosphere, saved resource, protected again environment, the social benefit obtaining is far longer than economic benefit.
Accompanying drawing explanation
Accompanying drawing 1 is structural representation of the present utility model;
In upper figure: oil-collecting main line 1, production wellhead 2, inlet union 3, a separator 4, high pressure connecting hose 5, second separator 6, controller dial plate 7, natural gas compressor 8, gas flowmeter 9, safety alarm device 10, ball-and-seat 11, outlet connection 12.
The specific embodiment
By reference to the accompanying drawings 1, the utility model will be further described:
The utility model comprises inlet union 3, gas-liquid separator, high pressure connecting hose 5, controller dial plate 7, natural gas compressor 8, gas flowmeter 9, ball-and-seat 11, outlet connection 12, by high pressure connecting hose 5, the sleeve gate of production wellhead 2 is connected with the import of gas-liquid separator, the outlet of gas-liquid separator is connected to natural gas compressor 8, controller dial plate 7 is located at a side of natural gas compressor 8, and the outlet of described natural gas compressor 8 is connected with oil-collecting main line 1 by gas flowmeter 9, ball-and-seat 11 and outlet connection 12.
Above-mentioned gas-liquid separator is connected to form by a separator 4 and second separator 6, first casing gas enters in a separator, make the fluid separation applications in gas, when the liquid level in a separator reach a certain height, ball float floating is opened the emptying of eliminator drain, and after discharging sky, ball float falls to closing drain, realizes automatic draining, then pass through second separator separation then.
The exit of above-mentioned natural gas compressor 8 is provided with safety alarm device 10, and the input of natural gas compressor 8 connects fire-proof motor.
Above-mentioned natural gas compressor 8 adopts two-stage compressors, and the pressure that makes casing gas is 1.7Mpa by 0.1Mpa liters of natural gas compressor import, and driven by motor compressor operating during work, boosts natural gas outer defeated.
The pressure intelligent control section that controller dial plate 7 connects has adopted node type anti-explosion pressure gage, when outlet pressure higher than set pressure time, the utility model quits work, pressure decreased in oil sets annular space is during to 0.08Mpa, the utility model quits work, pressure in oil sets annular space higher than set pressure time retracting device start working, guarantee the normal production of oil well pump, equipment safety even running.
Operating principle of the present utility model is: when oil well is normally produced, natural gas in tubing and casing annular space, constantly assembling rises causes well head, the sleeve pipe natural gas of will emerging, with high pressure connecting hose, respectively the sleeve gate of production wellhead 2 is connected with the import of a separator 4, the outlet of a separator 4 is connected with second separator 6, and the outlet of second separator 6 connects the import of natural gas compressor, and the outlet of natural gas compressor is connected with oil-collecting main line ball-and-seat entrance gate.When casing gas recovering device, casing gas enters a separator and second separator through sleeve gate, separated clean natural gas enters natural gas compressor compression along high pressure connecting hose, make gas pressure by the 0.1Mpa liter of import be 1.7Mpa, thereby it is inside and outside defeated to make to enter oil-collecting main line after natural gas via gas flowmeter 9 meterings after supercharging.
