高邮凹陷北斜坡中段发育4套辉绿岩侵入体,使地震资料品质变差。同时该区发育2套断裂系统,断层多解性强,圈闭落实困难。针对该区地震资料解释中的这两大难题,从研究辉绿岩地震反射特征及其与正常地层和断层地震反射的关系入手,探索出一套适合该区的地震综合解释方法,在该区的油气勘探中取得了显著的效果。 In the middle section of northern slope of Gaoyou sag, there are 4 sets of diabase intrusions, which deteriorate the seismic data quality. At the same time, there are two sets of fault systems developed in this area, and the faults are multi-solution and difficult to implement. Aiming at these two major problems in the interpretation of seismic data in this area, this paper starts from the study of the seismic reflection characteristics of diabase and its relationship with the normal stratigraphic and fault seismic reflection, and explores a comprehensive seismic interpretation method suitable for this area. The oil and gas exploration has achieved remarkable results.
