针对东海西湖深部地层压力解释精度低的问题,从东海西湖凹陷构造形成历史入手,研究了东海西湖异常压力机理,优选了西湖凹陷地层压力钻后检测方法。结果表明,钻后检测方法精度较高,满足了钻后评价要求。

The interpretation accuracy on the formation pressure in the deep layers of Xihu Depression is low in the East China Sea. In order to solve this problem, beginning from tectonic evolution history, study about the mechanism of abnormal pressure has been conducted, and detection method of pressure after drilling has been optimized. The study results indicated that the optimized method of pressure is high in accuracy, and can meet the requirements for post drilling evaluation.
