摘　　要：在讨论分析地质方法进行古地形恢复方法的基础上,研究了利用地震资料进行古地形恢复的技术方法。针对古地形恢复的几个技术关键问题:等时基准面的选取、压实校正系数的求取及差异构造校正进行讨论分析。综合利用各种基本地质成果,同时结合古构造、现今构造特点等,确定出研究区背景校正经验系数为0.2。就研究的方法对实际研究区目的层段进行了古地形的恢复。On the basis of discussion and analysis of the ancient landform recovering method using geological data, we have researched and used the ancient landform recovering method based on seismic data. For several technique key problems of the ancient recovering landform: how to select equitime base surface, find compact correction coefficient, and correct the divergence structure, we have conducted discussion and analysis . Using multipurposely various base geological results, uniting the age-old structure and current one characters, we have fit to background correction coefficient to be 0.2. Finally we have conducted on the ancient landform recover with the studied method.
