摘　　要：在回顾叠前深度偏移发展历程的基础上,概述了当前几类叠前深度偏移方法:克希霍夫积分法、波动方程法、逆时偏移。在分析叠前深度偏移的波场成像方法、适用性、近地表条件敏感性及存在问题的基础上,对比偏移剖面,比较不同偏移方法的成像效果,指出叠前深度偏移的发展方向,为以后的叠前深度偏移的研究提供参考建议。Based on reviewing the development of prestack depth migration,this paper has summed up several current prestack depth migration techniques,i.e.,Kirchhoff integration,wave equation,and reverse-time migration.On the basis of analyzing the prestack depth migration imaging method in such aspects as wavefield,applicability,sensitivity of the near-surface condition and existing problems,the authors made a comparative study of different migration imaging results by comparing the migration sections,indicated the development orientation of the prestack depth migration and put forward some proposals for further study of prestack depth migration.
