Abstract
The utility model provides a spray drainage type sleeve gas reclaiming device that is used for reclaiming natural gas in an oil well sleeve. A normally-opened electromagnetic valve 9, a normally-closed electromagnetic valve 2, a spray drainer 3 and a check valve 7 are arranged from an oil pipe well head 1; a pressure sensor 6, a natural gas flowmeter 5 and a check valve 4 are arranged from a sleeve four-way pipe 8. When the air pressure in the sleeve achieves a certain degree, raw oil enters the spray drainer 3 by a bypass; the raw oil flowing at high speed forms a negative pressure vacuum in the branch pipe cavity of the spray drainer, thus opening the check valve 4 so that volatile gas in the sleeve is inhaled and conveyed out with the raw oil along a trunk line, thus realizing the aim of reclaiming the sleeve gas. When the sleeve gas pressure is lower than the set value, the raw oil is conveyed out from the electromagnetic valve 9 and the check valve 7. The check valve plays the role of preventing the raw oil of the spray drainer from flowing into the sleeve. The drainage type sleeve gas reclaiming device has a simple structure, can be assembled conveniently, is energy-saving and safe, and almost requires no maintenance after being assembled.
Description
Technical field:
At present, many well casing gas can't enter the natural gas trunk line because of pressure is low, all enter in the atmosphere, both pollutant atmosphere, serious waste natural gas resource again.The utility model is used the simplest technology exactly, and the most energy-conservation device comes the recovery of casing natural gas.
Background technology:
Existing sleeve pipe gas recovery measure is broadly divided into three kinds: a kind of is the power drive plunger recovery of casing gas that utilizes oil pumper itself; This apparatus structure complexity, and only be applicable to pumping production, be not suitable for oil-immersed pump and recover the oil.Another kind is exactly to adopt air Compressor unit, enters gathering line after the pressure of sleeve pipe gas is increased, and this method investment is big, maintenance management expense height, power consumption are also big, and economic benefit is not obvious, therefore fails to be applied.Last a kind of method is: several sleeve pipe gas are communicated with, suppress certain pressure after, concentrate to reclaim; But after sleeve pipe built the pressure, the liquid level of oil well descended, and natural gas is dissolved in the crude oil, influences the efficient of oil well pump.
Summary of the invention:
Based on above analysis, in order to improve the deficiency in the above-mentioned sleeve pipe gas recovery measure, we design a kind of injection drainage type casing gas recovering device.
The technical solution of the utility model is: come out from oil pipe well head 1, normally open solenoid valve 9 is installed, normally closed solenoid valve 2 sprays flow diverter 3, trunk line stop valve 7; Come out to be equipped with from four-way junction of casing 8: pressure sensor 6, natural gas flowmeter 5, one way valve 4.When the air pressure in the sleeve pipe acquires a certain degree, pressure sensor sends signal, normally closed solenoid valve 2 is opened, normally open solenoid valve 9 time-delay closings make crude oil enter through bypass and spray flow diverter 3, and swiftly flowing crude oil forms negative-pressure vacuum in the arm cavity that sprays flow diverter, thereby one way valve 4 is opened, the interior Volatile Gas of sleeve pipe is sucked into, be transferred away along trunk line, realize the purpose of Volatile Gas in the recovery of casing with crude oil.When sleeve pipe gas was lower than setting value, pressure sensor sent signal once more, and normally open solenoid valve 9 is opened, normally closed solenoid valve 2 time-delay closings; The anti-crude oil that sprays flow diverter that flows to from the lower end, the effect owing to one way valve can not flow in the sleeve pipe.
The device that the utility model is designed, simple in structure, easy for installation, and energy-saving safety, post debugging is installed does not well need frequent maintenance; Owing to contain natural gas, be difficult for solidifying in the pipeline of conveying crude oil, carry easily.
Description of drawings:
Among the figure: 1-oil pipe well head, the 2-normally closed solenoid valve, 3-sprays flow diverter, 4-one way valve, 5-natural gas flowmeter, 6-pressure sensor, 7-trunk line stop valve.The 8-four-way junction of casing, the 9-normally open solenoid valve
The specific embodiment:
From crude oil well head 1, normally open solenoid valve 9, form the crude oil basic routing lines to trunk line stop valve 7; From normally closed solenoid valve 2, U-bend, injection flow diverter 3, form bypass lines to trunk line stop valve 7 again; From four-way junction of casing 8, pressure sensor 6, natural gas flowmeter 5, form gas lines to one way valve 4.Spray flow diverter 3 and vertically place, oil-in is last, and oil-out is descending the air inlet port level; One way valve 4 levels are installed in the air inlet port place of spraying flow diverter; The pipeline length that connects usefulness is adjusted according to the well head size.
During operate as normal, crude oil comes out from oil pipe well head 1, flows into oil transmission line by normally open solenoid valve 9, trunk line stop valve 7 (open mode).When the natural gas in the sleeve pipe reaches certain pressure, pressure sensor 6 sends signal, normally closed solenoid valve 2 is opened, normally open solenoid valve 9 time-delay closings, crude oil enters from bypass and sprays flow diverter 3, and swiftly flowing crude oil forms negative-pressure vacuum in the arm cavity that sprays flow diverter, thereby one way valve 4 is opened, the interior Volatile Gas of sleeve pipe is sucked into, be transferred away along trunk line with crude oil.When the gas pressure in the sleeve pipe was reduced to setting value, pressure sensor 6 sent signal once more, and normally open solenoid valve 9 is opened, normally closed solenoid valve 2 time-delay closings, and crude oil normally transfers out from the oil pipe basic routing line.
Natural gas flowmeter 5 is installed on the sleeve pipe air pipe, is convenient to measure the sleeve pipe tolerance size of recovery; Spraying flow diverter arm entrance installation one way valve 4, the crude oil of coming from bottom's backflow when preventing operate as normal flow in the sleeve pipe, influences output.
