Conveying is mixed together with oil, its operation principle is as follows：
The gas mixture that natural gas well is produced（Natural gas and oil）The medium entrance of the first catch pots of Jing 1
Preliminary Oil-gas Separation, the preliminary Oil-gas Separation bottom of the first catch pots of oil Jing 1 out are carried out into the first catch pot
The fluid outlet in portion and check-valves 31 enter the second catch pot lower chambers 22, in preliminary Oil-gas Separation natural gas out also
A small amount of oil drop is contaminated with, these are contaminated with the gas at the top of the first catch pots of natural gas Jing 1 of a small amount of oil drop
Outlet carries out secondary oil gas separation, the clean day that secondary oil gas are separated after flowing out into the second catch pot upper chamber 21
So the gas outlet of gas the second catch pots of Jing upper chamber 21 is pressurized into helical-lobe compressor 9, and secondary oil gas are isolated
Then the fluid outlet of the bottom of the second catch pots of Jing upper chamber 21 and check-valves 33 enter the second catch pot to the oil for coming
Lower chambers 22；
When oil liquid level in second catch pot lower chambers 22 reaches liquid-level switch operating position, liquid-level switch is moved
Make so that output control valve 4 is turned on, the high-pressure natural gas of the now output of helical-lobe compressor 9 are loaded into gas by output control valve 4
The control mouth of dynamic switch valve 5, pneumatic blow down valve 7 and pneumatic sewage drain valve 8 so that pneumatic on-off valve 5 ends, and make pneumatic blow down valve
7 and pneumatic sewage drain valve 8 turn on, now helical-lobe compressor 9 output the pneumatic blow down valves 7 of high-pressure natural gas Jing enter the second oil gas divide
From tank lower chambers 22, the oil in the second catch pot lower chambers 22 is purged, being run through pneumatic sewage drain valve 8, to drain into system defeated
Outlet 10, and aerofluxuss pipe network is discharged to after mixing with the high-pressure natural gas of the output of helical-lobe compressor 9 at System Outlet 10, from
And realize oil and gas multiphase flow；
When petroleum liquid potential drop in second catch pot lower chambers 22 is to liquid-level switch operating position, liquid-level switch
Reset so that output control valve 4 ends, and now the control mouth of pneumatic on-off valve 5, pneumatic blow down valve 7 and pneumatic sewage drain valve 8 is lost
Pressure, pneumatic on-off valve 5 is turned on immediately, and pneumatic blow down valve 7 and pneumatic sewage drain valve 8 then end immediately, and now helical-lobe compressor 9 is exported
High-pressure natural gas open only into System Outlet 10, the gas in the second catch pot lower chambers 22 then passes through pneumatic on-off valve
5th, air relief valve 6 backs into the second catch pot upper chamber 21 to reach pressure balance, and preliminary Oil-gas Separation and secondary oil gas are separated
Oil out can normally flow into the second catch pot lower chambers 22 again.
