优化油井套管气回收工艺

Optimization of casing gas recovery process in oil wells

超稠油生产过程中,要合理控制套压,套压过高会压低液面,影响油井产量,目前现场套管气回收流程与油井产出液为同一条管线,中间安装了一个单流阀,防止井液倒流回油套环空内。

It is necessary to control the casing pressure reasonably in the process of super heavy oil production because overpressure lowers the liquid level and affects the production of oil wells. The field casing gas recovery process is the same line with the oil well output liquid, therefore a single flow valve is installed in the middle to prevent the liquid back from flowing back to the casing annular pipe.
