摘要

白秋地区位于南阳凹陷东南部,构造背景是一个被后期北东向断层切割复杂化了的鼻状构造,该区地下构造复杂,断层发育,地层被多期断层交汇切割,同时埋深又比较大,使得常规地震处理不能对该地区地层准确成像。叠前深度偏移技术在白秋地区的应用,提高了区内地层的成像精度,精细刻画了较小的断层断块,满足了地质人员的解释需求。
Located in the southeast of Nanyang sag,the tectonic setting of Baiqiu region is a complicated nose-like structure cut by a late northeastern fault.The underground structure of this region is complex,with faults development.As the formation is of intersection cutting by multiphase faults,the inside structure is very complicated.At the same time,due to the bigger buried depth,by use of the conventional seismic processing,the formation imaging accuracy of this region can not be obtained.While with prestack depth migration technology applied in Baiqiu region,the precision of the formation imaging has been improved and the minor fault block has been accurately described,which therefore meets the demands of the interpretation for geological personnel.
