| Abstract: | The prestack depth migration is an ideal technique for improving seismic imaging of complex areas and drastic horizontal velocity changes. The basic theory and technical characteristics of four fundamental prestack-depth-imaging methods are described in this paper. The problems and the newest advances both in China and abroad are also discussed. It is hoped that this study can help us find the key problems and seek suitable imaging techniques for areas of complex geological conditions. |
