摘要
文章通过对江苏油田高邮金湖凹陷以往三维地震采集情况及效果分析,探讨下步在高邮凹陷南断阶、北斜坡、金湖凹陷安乐-桐城断裂构造带、闵南-杨村断裂带、石港断裂带等低信噪比地区以提高资料信噪比为主要采集方法,其他地区以提高资料分辨率为主要采集方法,并对隐藏油气藏、火成岩地区的地震采集方法、对策进行了分析,对高邮金湖下步三维地震采集有一定的意义。
Through analyzing previous 3D seismic acquisition performed in Gaoyou-Jinhu Sag of Jiangsu Oil Field and relevant results,this paper discusses the main acquisition method to be applied for improving signal-to-noise ratio in the south fault terrace and the north slope of Gaoyou Sag,Anle-Tongcheng fracture structure,Minnan-Yangcun fault zone,Shigang fault zone and other areas with low signal-to-noise ratio,as well as the main acquisition method adopted in other areas to improve the resolution of seismic data.Meanwhile,this paper analyzes seismic acquisition methods and measures to be adopted in hidden oil-gas deposits and igneous rock areas,which are of great significance to 3D seismic acquisition to be carried out in Gaoyou and Jinhu.
