摘要
叠前深度偏移是理想的改善复杂地区和强横向速度变化的地震资料成像技术,笔者就4种典型叠前深度偏移方法的理论基础与技术特点,存在的问题及国内外最新进展进行了讨论。
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.
