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 processing result acquired is equivalent to that got by some similar processing software,and partially better than some similar processing software.
