鄂尔多斯盆地侯、杏区裂缝与地应力研究在注水开发中的应用

Research on Reservoir Crevices and Crustal Stress of Houshi and Xinghe in Ordos Basin and Application of Their Water Injection

阐述了鄂尔多斯盆地侯市、杏河两个含油区块三叠系延长统裂缝性质、类型、走向及裂缝分布规律、裂缝成因及其与地应力关系,并着重分析油层内裂缝特征对油层本身及产出能力的影响,从而为调整注术开发方案、防止油层水淹、提高水驱油能力提供依据。

This thesis relates the nature, types and strike of the Triassic extended crevices of Houshi and Xinghe oil-bearing areas in Ordos Basin , and the distribution rules and causes of the crevices and their relations with crustal stress. Particularly, it analyzes the influences of the crevices features in oil reservoir on itself and its production capacities, and thus provides bases for adjustment of water injection plans, prevention of water submergence of oil reservoir and raise of the ability of water driving oil.
