东辛油田中部是一个复杂断块油藏,在经历了近40年开发后,目前已进入高含水开发阶段,储层丰度变差,剩余油分布零散等矛盾日渐突出,油藏稳产难度越来越大,针对复杂断块油藏高含水期的开发特征及存在的开发矛盾,提出了九种挖潜稳产技术,现场生产实践证明,它对于减缓老区递减,实现断块油藏高含水期稳产效果显著。
After nearly 40 years of development, the central East Sinh Oilfield is a complex fault block reservoir. At present, it has entered the stage of high water-cut development, the reservoir abundance has become worse, and the remaining oil distribution has become more and more prominent. The stability of the reservoir is more difficult According to the development characteristics and existing development contradictions of high water cut stage in complex fault block reservoirs, nine kinds of potential tapping potential technologies are proposed. The field production practice proves that it is effective in reducing the decrement of old areas and realizing the stable production in the high water cut stage of fault block reservoirs Significant effect.
