为解决凝析油气藏在开采后期由于地层压力自然递减加快,开采难度加大,低压天然气无法进入输送管道,大量天然气自然放空以增加凝析油采收率的问题。塔里木油田公司牙哈作业区多年来一直致力于低压天然气的回收利用的研究,通过建立增压装置对低压天然气进行回收利用。文章通过现场实际的开采历程来论述天然气压缩回收再利用在油气田开采过程中的有效实施性,以新技术新工艺来达到提高凝析油采收率、减少资源浪费、降低大气污染、增加经济效益的目的。
In order to solve the problem that condensate reservoirs naturally decelerate due to formation pressure later in the mining period, exploitation is more difficult, low-pressure natural gas can not enter the pipeline and a large amount of natural gas is naturally vented to increase condensate recovery. Tarim Oilfield Company Yaha operation area for many years has been committed to low-pressure natural gas recovery and utilization of research, through the establishment of booster devices for low-pressure natural gas recycling. The paper discusses the effective implementation of natural gas compression recovery and recovery in the process of oil and gas field exploitation through the actual mining history of the field, with the new technology and new technology to improve the recovery rate of condensate oil, reduce resource waste, reduce air pollution and increase economic benefits the goal of.
