文 90断块区经过十二年的注水开发,已进入高含水期,开发效益变差。文章在认真分析油藏开发现状的基础上,充分运用相关技术,开展油藏精细研究,重新落实构造,弄清储层分布规律,对该块实施滚动扩边,部暑的新井高产高效,改善了区块的开发效果,取得了较好的经济社会效益。

W90 fault block zone has been exploited for 12 years through water-injection. It has entered high water-containing period and its production has already declined. On the base of analyzing actuality of oil reservoir, the workers fully handle correlative technology, study oil reservoir and realize new structure. They make clear the regularity of container horizon and expand the border of the fault block. Meanwhile, they deploy high output and efficiency well. Exploitation effect of the fault-block is improved. It gets better economic and social effects.
