低序级断层识别技术在潜江凹陷西斜坡滚动勘探中的应用

Application of low-level fault identification technique in progressive exploration of west slope of Qianjiang Depression

潜江凹陷西斜坡地区油气资源丰富,储层发育,主要油藏类型为复杂断块构造油藏。近年来,充分运用大量动、静态资料,应用基于地震资料目标处理、模型正演及属性分析的低序级断层识别技术,开展精细构造解释,落实该区构造格局及局部构造特征,结合储层展布及成藏规律认识,开展滚动勘探研究,取得较好的效果,形成复杂断块油藏滚动勘探思路与方法,对复杂断块油藏滚动勘探研究具有一定的推广意义。

The west slope area of Qianjiang depression is rich in oil and gas resources,with the complex fault-block structural reservoir as the primary reservoir type.In recent years,we carried out the fine structure interpretation by using a large volume of dynamic and static data and applying the low-level fault identification technique based on the target processing of seismic data,forward modeling and attribute analysis.The structural framework in the area and local structural characteristics were determined.Coupled with the insight of the reservoir distribution and hydrocarbon accumulation,the study of progressive exploration was conducted,achieving good results.The idea and method for the progressive exploration of complex fault block reservoirs are established,which is worth wider application in the progressive exploration of complex fault block reservoirs.
