Description
Technical field
The utility model relates to technical field of petroleum extraction more particularly to producing well energy-saving air release valves.
Background technique
In oilfield applications, when oil well production, oil is gentle while being discharged out of well, then they are collected from a bite mouth oil well
In get up, and separate oil is gentle, then through preparatory processing become qualified former oil and gas store respectively or
It is transported to oil plant, the amount (m for the natural gas that crude oil per ton is taken out of3), referred to as oil-gas ratio.That is each stroke of oil well pump
It aspirates the oil that is not all to come up and contains some gas, the working efficiency of such oil well pump can reduce, the well high for gas-oil ratio, take out
The working efficiency of oil pump can be lower.
Summary of the invention
Purpose of the utility model is to solve disadvantages existing in the prior art, and the producing well proposed is put with energy conservation
Air valve.
The utility model uses following technical solution：A kind of producing well energy-saving air release valve includes valve housing, valve housing
Side be fixed on oil pipe, location nut is connected in the outer set upper side of valve, valve housing lower end is equipped with import and oil jacket space phase
Logical, the top of valve housing is equipped with venthole, and venthole is communicated with oil pipe inner cavity, and deflation spool is equipped in valve housing top, deflates
Spool be it is hollow, on deflation spool wall circumferentially on set an exhausting hole, through-hole is communicated with venthole, deflation spool lower end connect
Have a check-valves, check-valves lower end is connected with flow divider valve core, flow divider valve core be it is hollow, in flow divider valve core top wall circumferentially on set one
Stomata is discharged into, the ring cavity between air inlet and flow divider valve core and valve housing communicates, and float, the outer wall of float are equipped in flow divider valve core
There is gap between flow divider valve core inner wall.
Float in above scheme is hollow, only one open end and downwards, and float upper end is hemispherical.
The beneficial effects of the utility model are：Energy-saving air release valve both may be implemented to put casing atmospheric pressure, reduce flowing bottomhole pressure (FBHP),
It can use sheath gas again and enter oil pipe and play the oily tube fluid of carrying and rise, to reduce the mesh of oil pumping pump work energy consumption
's.Float in the application density of material itself is big, and by hollow machine-shaping, density is and resistance to less than 0.84 in fluid
High temperature, it is high pressure resistant, be sealed, high temperature resistant is up to 200 degree or more, high pressure resistant 25KG in the operating condition for float, and itself is indeformable,
The utility model only deflates under high-temperature high-pressure state and does not drain the oil.

Specific embodiment
Below in conjunction with attached drawing 1, the present invention will be further described, and producing well energy-saving air release valve includes valve housing 1,
The side of valve housing 1 is fixed on oil pipe 11, and location nut 5,5 pairs of deflation spools 3 of location nut are connected in 1 upper end of valve housing
There is position-limiting action, 1 lower end of valve housing is equipped with import 10 and communicates with oil jacket space, and gas enters energy conservation by import 10 and deflates in well
The top of valve, valve housing 1 is equipped with venthole 2, and venthole 2 is communicated with oil pipe inner cavity, by the gas of energy-saving air release valve by outlet
Hole 2 enters and oil well is discharged in oil pipe, and deflation spool 3 is equipped in 1 top of valve housing, and deflation spool 3 is hollow, deflation spool
On 3 walls circumferentially on set an exhausting hole 8, through-hole 8 is communicated with venthole 2, and 3 lower end of deflation spool is connected with check-valves 6, check-valves
6 prevent the liquid reflux in oil pipe, that is to say, that liquid will not flow to oil jacket space, check-valves by energy-saving air release valve by oil pipe
6 lower ends are connected with flow divider valve core 4, flow divider valve core 4 be it is hollow, in 4 top wall of flow divider valve core circumferentially on set one and discharge into stomata 9,
Ring cavity between air inlet 9 and flow divider valve core 4 and valve housing 1 communicates, and is equipped with float 7 in flow divider valve core 4, the outer wall of float 7 with
There is gap between 4 inner wall of flow divider valve core.Float 7 be it is hollow make 7 density of float less than 0.84, below float 7 when feed liquor due to
Density can float closing energy-saving air release valve channel less than 1 float 7, and thus energy-saving air release valve is only vented not oil extraction, and float 7 only has
One open end and downwards, 7 upper end of float is hemispherical, this shape matches sealing effect with the valve base inner wall of check-valves 6
More preferably.
Fig. 2 is deflation status：When reaching certain pressure in casing, gas by import 10 enter energy-saving air release valve, one
Portion gas enters air inlet 9 by the ring cavity between flow divider valve core 4 and valve housing 1, enters check-valves 6, valve ball by air inlet 9
It is jacked up, gas enters oil pipe by through-hole 8, venthole 2 and is discharged, and another part gas is by ring between float 7 and flow divider valve core 4
Chamber enters check-valves 6, and valve ball is jacked up, and gas enters oil pipe by through-hole 8, venthole 2 and is discharged, when gas enters the application
Since float does not rise under the effect of gravity, natural gas is discharged by venthole 2, and gas can carry partially liq in oil pipe and rise
To the effect of lifting liquid.
Fig. 3 is well-flushing status diagram：Cause on liquid level when covering liquid in pipe rising or reservoir productivity increase when well-flushing
It rising, liquid enters flow divider valve core 4 by import 10, and the float in flow divider valve core 4, which rises, realizes sealing with the valve seat of check-valves 6,
Set liquid in pipe does not enter in oil pipe, achievees the purpose that not tapping of only deflating.
