针对文留油田气藏采出程度高、气层压力低、井筒积液严重的现状,实施了气举排液采气增产配套技术,主要有:半闭式气举、低压气井气层保护增产技术和高压气井气进行气举排液采气技术,取得显著增产效果。解决了文留油田低压气井长期低效开采的难题,为同类气田低压气井高效开采、提高气藏采收率提供了有效途径。

In view of high degree of reserve recovery, low pressure and serious liquid loading of Wenlai gas reservoir, drainage gas recovery by gas lift was used and obtained obviously effectiveness, its necessary technology includes semiclosed gas lift, protection and increasing production technology of low pressure gas well and drainage gas recovery by gas lift technology of high pressure gas well. This research has provided a effective approach for the same gas well.
