The utility model discloses a kind of pressure relief device of automatic release set gas, including pressure-control valve, pressure gauge, throttle valve, high pressure line, main gas pipeline and well wellbore, well wellbore top side connects main gas pipeline, the input terminal of the pressure-control valve is connected on the well wellbore of main gas pipeline lower part, the output terminal of the throttle valve is connected on main gas pipeline, is connected between the input terminal of the throttle valve and the output terminal of pressure-control valve by high pressure line.Compared with prior art, has the following advantages：Design is rationally, structure is novel, it is easy to make, and reliable in action is highly practical.Its natural gas that can meet to have more than needed after oil gas high pressure can be by the present apparatus automatically into oil-collecting main line, and ecological protection avoids pollution of the pipe gas to environment, avoids the waste of the energy, realizes the centralized collection of oil gas and waste.
Description
Technical field
It the utility model is related to a kind of pressure relief device, and in particular to a kind of pressure relief device of automatic release set gas.
Background technology
In crude oil production, reservoir fluid is in Wellbore Flow, with the reduction of fluid flow pressure, the solution gas in crude oil
Separation, enters oil sets annular space, forms casing gas, and the air column with certain pressure is formed on top.In actual production,
In order to prevent casing pressure it is excessive cause oil pumping Pump Suction Nozzle pump intake pressure it is too low, it is necessary to periodically relief sleeve gas with reduce gas to take out
The influence of oil pump.In " 95 " in the past, the of a relatively high mechanical oil well of production gas-oil ratio, generally takes and puts casing gas reduction set
Pipe pressure, mitigates influence of the gas to production, achievees the purpose that to improve pump efficiency increase yield.At that time without stringent outer supply
Task, does not possess under natural gas storing condition yet, and high gas-oil ratio (HGOR) well puts casing gas production, oil well enhancing efficiency by relying on tapping internal latent power of can yet be regarded as
Desirable means.With the pay attention to day by day that oil field produces natural gas, the loss and harm for being vented casing gas progressively display.
In crude oil production, reservoir fluid is in Wellbore Flow, and with the reduction of fluid flow pressure, the solution gas separation in crude oil, enters
To oil sets annular space, the separation gas formed is known as casing gas.Casing gas with unexpected row, without sleeve valve production situation according to
So very universal, this not only wastes substantial amounts of solution gas resource, but also polluted air.Ecological environment is destroyed.
The content of the invention
The purpose of this utility model is aiming at defect existing in the prior art, there is provided a kind of pressure release of automatic release set gas
Device.
Its technical solution is：The pressure relief device of automatic release set gas, including pressure-control valve, pressure gauge, throttle valve, high pressure
Pipeline, main gas pipeline and well wellbore, well wellbore top side connect main gas pipeline, the input of the pressure-control valve
End is connected on the well wellbore of main gas pipeline lower part, and the output terminal of the throttle valve is connected on main gas pipeline, described
Connected between the input terminal of throttle valve and the output terminal of pressure-control valve by high pressure line.
Wherein, the input terminal of the pressure-control valve is equipped with pressure gauge.
The pressure-control valve is spring micro-open type safety valve or self-contained pressure regulator.
The throttle valve is angle check valve.
Compared with prior art, has the following advantages：Design is rationally, structure is novel, it is easy to make, and moves
Make reliably, it is highly practical.Its natural gas that can meet to have more than needed after oil gas high pressure can be raw by the present apparatus automatically into oil-collecting main line
State has been protected from pollution of the pipe gas to environment, avoids the waste of the energy, realizes the centralized collection of oil gas and waste.
Brief description of the drawings
Fig. 1 is a kind of structure diagram of embodiment of the utility model.
Embodiment
With reference to Fig. 1, a kind of pressure relief device of automatic release set gas, including pressure-control valve 1, pressure gauge 2, throttle valve 3, height
Pressure pipeline 4, main gas pipeline 5 and well wellbore 6,6 top side of well wellbore connect main gas pipeline 5, the pressure control
The input terminal of valve 1 is connected on the well wellbore 6 of the main downside of gas pipeline 5, and the input terminal of pressure-control valve 1 is equipped with pressure gauge
2.The output terminal of the throttle valve 3 is connected on main gas pipeline 5, and the input terminal of the throttle valve 3 is defeated with pressure-control valve 1
Connected between outlet by high pressure line 4.
During operation, when with the increase of pressure, oil gas more than needed is full of stream to oil gas in well head in well wellbore 6, the present apparatus
In 6 times installation pressure-control valves 1 of well wellbore, pressure-control valve 1 is spring micro-open type safety valve or self-contained pressure regulator,
Its pressure is set below or equal to 1.6MP（This numerical value can be set according to well site actual conditions）.When oil pump rod is transported up and down
When dynamic, when oil-air pressure is greater than or equal to setting value, for oil gas by pressure-control valve 1, pressure piping 4 enters throttle valve 3, described
Throttle valve 3 selects angle check valve；At this time, throttle valve 3 automatically opens up, and oil gas enters main appendix by high pressure oil pipeline 4
Road 5.
The natural gas that the present apparatus meets to have more than needed after oil gas high pressure can be set by the present apparatus automatically into oil-collecting main line, the present apparatus
Meter is reasonable, structure is novel, and securely and reliably, ecological protection avoids pollution of the pipe gas to environment, avoids the waste of the energy, realizes
The centralized collection of oil gas and waste.
