Oilfield wellhead casing gas recovery and crude oil production increase and environmental protection and energy saving device

  • Causes and hazards of casing gas in oil fields

    Source of casing gas: A large amount of natural gas dissolved in formation oil at high temperature and high pressure is called dissolved gas. In crude oil production, as the fluid flow pressure decreases, the dissolved gas in the crude oil separates into the annular space of the oil jacket, and the resulting separated gas is called casing gas.

    Casing gas hazard: Casing gas forces the oil well to lower the fluid level, which reduces the effective production pressure and productivity of the oil well. A part of it enters the pump cavity of the oil well with the liquid flow and occupies a certain amount of space in the pump cavity, which affects the pump efficiency. In severe cases, "air lock" may occur, which makes the oil well pump unable to work and affects the normal production of the oil well.

    The traditional method uses venting to solve the problem of excessively high casing pressure in oil wells. Natural gas destroys the atmospheric ozone layer 21 times as much as CO2, which will cause serious environmental problems.

    Field test application at Xianhe Oil Production Plant of Shengli Oilfield

    According to the actual situation of the Xianhe oil production plant in Shengli Oilfield, combined with the prediction of geological productivity, the stable gas flow rate of the casing, and the multi-purpose feature of the device, select the wells that cannot enter the production process at the Xianhe oil production plant for installation and use.

    The automatic wellhead gas recovery device of the oilfield was installed on November 16, 2018 in the wells He 60-X51, He 60-X52, and He 60-X53 in the Haoxian management area of ​​the Xianhe Oil Production Plant. Increase, the effect is very satisfactory.
