For the limitation to protection scope of the present invention.
Fig. 1 shows that the oil well casing gas of the present invention is pressurized the structural representation of collecting device.
Referring to Fig. 1, oil well casing gas supercharging collecting device of the invention includes housing 1.The housing
The gas-liquid being connected with oil well casing is provided with 1 and is automatically separated pipe 2.Oil gas from oil well casing
The separation that gas and liquid are carried out in pipe 2 is automatically separated in the gas-liquid.
In the present invention, the gas-liquid is automatically separated outside pipe 2 and is arranged with antifreeze constant temp mozzle 3.
There is the gas imported from compressor 9 described later inside the antifreeze constant temp mozzle 3, with certain
Temperature, can prevent winter low temperature from causing the gas-liquid to be automatically separated the inner icing of pipe 2.
The gas-liquid, which is automatically separated in pipe 2, is provided with filter core 4.The filter core 4 into
It is iron oxide to divide, can be for the sulphur in removal natural gas.
The gas-liquid is automatically separated the lower end of pipe 2 and is connected with being automatically separated drain pump 5.Liquid reaches
When a certain amount of, it can be automatically drained out by the drain pump 5 that is automatically separated.The row of being automatically separated
Liquid device 5 is connected with oil pipe, is exported the liquid isolated by oil pipe.
The gas-liquid is automatically separated the upper end of pipe 5 entering by tracheae and two grades of voltage stabilizing separators 6
Mouth is connected.Two grades of voltage stabilizing separators 6 are used to carry out two grades of voltage stabilizings to the gas separated
Separation.
The gas-liquid is automatically separated between pipe 2 and two grades of voltage stabilizing separators 6 and is provided with first
Resistance to pressure gauge 7 and the gauge table 8 of shaking.It can be observed and isolated by the described first resistance to pressure gauge 7 that shakes
The pressure of the gas come.The amount for the gas that can be separated by the gauge table 8.
So, can immediate observation casing pressure, instantaneous delivery and device gas, with real-time monitoring and control,
Do not influence job execution.
