摘要
针对常规地震资料处理中 ,叠后时间偏移不能解决倾斜界面的非共反射点叠加 ,以及叠前深度偏移对速度模型的要求太高等问题 ,在胜利油区车镇凹陷埕南断裂带 ,应用叠前时间偏移处理技术 ,解决了陡倾角断面及中、古生界资料的成像等难题 ,取得了较好的处理效果。
In usual seismic data processing, poststack time migration can not get the noncommon reflection stack results in the case of a tilted interface, and prestack depth migration needs too much in velocity models. In order to deal with these problems in the seismic data processing of Chengnan fracture belt in Chezhen sag of Shengli oilfield, prestack time migration technique was used, and good results were achieved in the imaging of steep dip fault plane and MesozoicPalaeozoic strata.
