Study on the Technology of Improving the Development Effect of “Two Lows" Unit

本文立足于江汉油区“双低”单元自身地质与开发特征 ,选择部分具有代表性的“双低”单元 ,着重研究其注水开发特征及油水运动特征 ,包括注入水推进的不同类型及其对开发效果的影响 ,在此基础上分析目前江汉油区“双低”注水开发中存在的主要问题 ,并提出一些具有针对性的注采调整意见 ,在实施过程中取得了一些效果 。

Based on the geological and development characteristics of the “two lows' units in Jianghan oil-bearing block, this paper focuses on the study of the development al feature through water injection and oil and water movement features for the selected representative “two lows' units, including the advance types of injected water and its influence on the development effect. The current main problems for developing the “two lows' units are analyzed and some pertinent adjustment schemes for water injection and oil production are thus presented. Some effects have been obtained and viewpoints have been got during the implementation of the schemes.
