| 摘 要： | 三维叠前深度偏移技术是解决复杂构造和速度横向变化剧烈地区地震资料成像问题的有效手段。文章介绍了STseis系统Kirchhoff积分法叠前深度偏移的基本原理及处理流程,给出了应用该系统对胜利油田BS6地区三维地震资料叠前深度偏移处理的效果。与常规叠后时间偏移剖面相比,叠前深度偏移资料断面形态更加清晰,潜山及内幕成像更加清楚;与国外同类软件相比,STseis处理效果相当,并部分地超越了国外同类产品。

| Abstract: | 3D prestack depth migration is the most effective way to image complex structures and seismic data from the area where the change of transverse velocity is large.It introduces the prestack depth migration techniques of STseis software system and its processing flow,and presents the processing results by using the real seismic data from BS6 area.The shapes of fracture surface and the images of buried hill and its inside are clearer than that processed by the conventional poststack time migration,the processi... |
