摘要
断块油田因断块发育 ,进入高含水采油阶段时间较早。断块油田在高含水期阶段纵向和平面非均质严重 ,层间矛盾更加突出 ,没有动用的剩余油更加分散、破碎 ,产量递减速度加快 ,水油比增长快。根据断块油田在高含水期的开采特点 ,分析了有代表性断块油田的成功开采经验 ,对断块油田在高含水期的开采特点进行仔细研究 ,提出了断块油田在高含水期改善注水开发效果的有效途径。
Fault-block reservoir is composed of fault-block, it is fault-screened oil pool, nature energy is not enough and is short of supplement. Fault-block reservoir is at high water-cut stage quickly. Exploitation characteristic of fault-block reservoir is particular at high water-cut stage. reservoir is a serious heterogeneity reservoir, contrary between layers stand out,the distribution of remaining oil is not regular, production decrease swiftly and water cut increase. On the basis of exploitation characteristic of fault-block reservoir at high water-cut stageand exploitation practice of some typicalfault-block reservoir, some effective methods is put forward to enhance developmentefficiency of fault-block reservoir at high water-cut stage. In this paper, some methods and results could be used in similarreservoir.
