Problems solved by technology
During use, when the amount of gas produced is small or the amount of gas used is large, the liquid in the shell rises, enters the gas outlet pipe and flows out, causing pollution and leakage. The safety of gas use is low. When the gas outlet pipe is blocked, it will affect normal production

The invention provides a novel oil-gas separator, belonging to a device for oilfield production. The novel oil-gas separator comprises a shell, wherein a liquid inlet pipe is installed on one side of the lower part of the shell; a liquid outlet pipe is installed on the other side of the lower part of the shell; a partition board is installed in the upper part of an inner cavity of the shell; a taper valve shell is fixedly arranged on the middle part of the partition board; the lower part of the taper valve shell is provided with a water catching barrel; a taper spool is installed in the taper valve shell; the lower end of the taper spool is connected with a floating ball; a guide rod is installed on the upper part of the taper spool; an exhaust hole is formed in the taper valve shell above the taper spool; a pressure reducing valve shell is installed on the partition board as well; a valve ball is installed in the pressure reducing valve shell; a liquid return hole is formed in the taper valve shell as well; the upper end of an air outlet pipe is located above the partition board; the lower end of the air outlet pipe is communicated with an air outlet; and a separation umbrella is arranged above a liquid outlet of the liquid inlet pipe. The oil-gas separator is rational in structure and good in separation effect; the entrance of extracted liquid into the air outlet pipe can be effectively prevented; and therefore, the environmental pollution resulting from the entrance of extracted liquid into the air outlet pipe is prevented and the normal production of an oilfield is guaranteed.
Description
technical field [0001] The invention provides a device for oil field production, especially an oil-gas separation device. Background technique [0002] The production fluid produced by the pumping unit from the oil well contains crude oil and a small amount of natural gas. Natural gas can be separated and used as fuel, and the liquid in the pipeline can be heated to reduce oil transportation resistance. There is a housing on the current gas-liquid separator, and a liquid inlet pipe is installed on one side of the lower part of the housing, and a liquid outlet pipe is installed on the other side. lead out. After the liquid enters the shell, a gas space is formed above the inner cavity of the shell, and the gas in this space flows out through the gas outlet pipe. During use, when the amount of gas produced is small or the amount of gas used is large, the liquid in the casing rises, enters the gas outlet pipe and flows out, causing pollution and leakage. The safety of gas us...
