油田进入特高含水开发后期,剩余油高度零散,主要集中在挖潜难度较大的厚油层顶部及断层边部等部位。本文针对A断层周围套损严重油水井报废、关井区域,通过深化地质研究,强化潜力分析,优化方案设计,实施更新、侧斜等手段,努力挖潜A断层附近剩余油,取得了较好的效果。 The oilfields entered the late stage of ultra-high water-cut development and the remaining oil is highly fragmented, mainly concentrating on the top of thick oil reservoirs and the edge of faults that are more difficult to tap. In this paper, aiming at the area of ​​oil and gas wells that have been damaged and damaged in zone A of the fault seriously, the remaining oil in the vicinity of Fault A is to be tapped by deepening the geological research, strengthening the potential analysis, optimizing the scheme design, effect.
