Gas reservoir development indicates that edge water drive gas reservoir is much lower in recovery efficiency compared to fixed volume gas reservoir.
为提高边水驱气藏的采收率,目前传统的做法是控制气藏开采速度、保持气藏能量、尽可能地延长气藏的无水采气期和控制边水的入侵速度,这种开采方式最终造成边水气藏水淹时的废弃压力很高,而采收率较低的局面。
In this paper,techniques of tracer monitoring are successfully applied in development exploitation of edge water drive reservoir,the course and velocity of edge water propulsion are confirmed.
