Description
Technical field
The utility model relates to oil extraction in oil field tree wellhead assembly, specifically a kind of well casing gas automatic decompression device.
Background technology
The pressure of conservative control well casing gas, can reduce the impact of gas on oil well pump, is also the main technological means of oil field stable high yield.The hypertonia of casing gas produces disadvantageous factor to oil well and is mainly manifested in: one is the coefficient of fullness affecting oil well pump, due to the also solution gas of remaining some and compressed gas in the pump chamber of down stroke end, pressure after upstroke starts in pump chamber can not reduce very soon due to gas expansion, causes standing valve to be opened slow.Two is that well fluid level reduces, and cause oil well pump submergence too low, crude oil can not be full of seating nipple in time, thus pump efficiency is reduced.
And the method controlling well casing gas is at present, when pressure increase is to certain value, operator opens sleeve valve to well head, casing gas is put in air, so not only causes environment pollution, also cause the wasting of resources.
Summary of the invention
The purpose of this utility model is exactly the defect for prior art exists, and devises a kind of well casing gas automatic decompression device.
The utility model is realized by following technical proposals:
Well casing gas automatic decompression device, comprising: pressure release assembly, valve seat, cone valve, spring, regulator bolts, sealing ring, exhaust short circuit, air inlet port, hoop, seal groove, meter connector, pressure meter, supporting positive cover; Its well casing gas automatic decompression device pressure release assembly is cylindrical structure, inside establish stepped hole, pressure release assembly top is provided with internal thread, be connected with the external screw thread be provided with in "T"-shaped shape regulator bolts, lower-left end is provided with the air inlet port of circular tube shaped, and the internal thread that air inlet port is provided with hoop right-hand member is connected, hoop left side is provided with the seal groove in trapezoidal shape, bottom righthand side is provided with the meter connector communicated with air inlet port, and meter connector is equipped with pressure meter, and upper right side is provided with circular tube shaped exhaust short circuit.
Communicate with the intercommunicating pore between air inlet port, meter connector bottom the stepped hole that its well casing gas automatic decompression device pressure release assembly inside is provided with, valve seat is sitting on the step of stepped hole.
The stepped column construction of its valve seat, the tapered shape in valve seat lower surface, top is circumferentially provided with sealing ring, center, upper surface is provided with the bellmouth at 45 degree of oblique angles, bellmouth and cone valve cooperatively interact, supporting positive cover and spring are equipped with in cone valve top, are fixed in the stepped hole of pressure release assembly by regulator bolts.
The beneficial effects of the utility model are: can regulate casing pressure, solve the impact of casing gas on oil-well pump of oil well, to ensure the rational submergence of oil well pump, not only increase the coefficient of fullness of pump, also reduce the labour intensity of worker, there is higher economic benefit and social benefit.
