摘　　要：叠前深度偏移是解决复杂地质构造成像的有力手段 .关于叠前深度偏移方法的研究一直是勘探地球物理研究的热点和难点 .本文在收集、整理国内外有关研究资料的基础上 ,有选择地对若干类型方法研究背景及现状、基本原理及方法特点等进行分析 ,目的在于作为研究工作的起点 ,把握叠前深度偏移方法的发展趋势 。The prestack depth migration is a powerful tool for complex structure imaging. Research on prestack depth migration method is not only the hot but also the difficulty in geophysical prospecting. Based on the study of relative material published in recent decade,the current situation and progress on ray tracing method research,and remark on several selected typical methods is provided in this paper. We hope this work would be a help to get some knowledge of tendency of migration method,to seek for imaging methods that are suitable for the complex geological conditions in our country.
