义东油田沾四区“双低”储层改造措施研究

The Reconstructed Development Program of Oil Stratum Unit of Low Recovery Percent and Oil Production in Zhansi Block,Yidong Oilfield

义东油田沾四区是一个低采出程度、低采油速度的“双低”单元。在介绍了该区油藏储层特征的基础上,对区块开采中存在的主要问题进行分析,重点探讨区块精细地质研究的方法和采油综合配套技术的应用,实现了区块开发的稳产。

Zhansi Block of Yidong Oilfield is a'dual low' (low recovery percent and oil production) oil stratum unit. In this article, Firstly we introduce the district's reservoir characteristics,then analysis the major problems existed in the process of production, the emphasis and the methods which are involved in the delicate geological research of the block and the application of compound technologies used in oil production finally, the production of the block is developed stablly.
