摘要
对廊固凹陷泥质岩的异常压力和封闭性能的关系进行了研究.研究表明,在异常压力条件下所形成的良好泥质岩盖层有利于油气聚集.并分析了该凹陷泥质岩盖层的封闭特征,异常压力和微裂缝能控制盖层的封闭性能.
This paper studies the relationship between the abnormal pressure and sealing characteristics of shale in Langgu sagging. A good cap rock formed under the abnormal pressure is favorable to the accumulation of hydrocarbons and its sealing characteristics is analyzed. The result shows that the abnormal pressure and microfracture controlled the distribution of cap rock.
