摘要
为了提高试采放空天然气的利用率,考虑将不能输送的放空低压气进行技术增压,达到输送压力后,使其进入油气处理装置进行分离,其中一部分通过注气压缩机回注至地层,保持地层压力,提高油田凝析油采收率和延长油气田开发时间,实现低压气的高效利用。对站外试采井的低压放空气进行增压回收,减少了天然气资源浪费,实现了向资源节约型、环境保护企业的健康发展。
In order to improve the utilization rate of trial venting natural gas,it is considered to supercharge the undeliverable low-pressure venting gas.When the deliverable pressure is reached,the gas is transported into oil and gas processing device to be separated,part of which being reinjected into strata through gas injection compressor to sustain the pressure of the strata,to improve the recovery efficiency of gas condensate in oil and gas field and to extend the development time of oil and gas field,thus realizing the efficient use of the low-pressure gas.Through recycling the low-pressure venting air from trial mining wells outside the station with supercharging,resource wasting of natural gas is reduced,achieving healthy development of resource saving and environment protecting enterprise.
