摘要
随着勘探和开发对地震资料处理成果的要求越来越高,常规叠后时间偏移处理技术的缺陷日益显现出来。为了解决这个难题,推出了叠前深度偏移处理技术。文章从该项技术的提出、主要技术方法阐述、处理流程制定以及应用实例分析等几个方面系统地介绍了近年来在叠前深度偏移处理技术的应用上所做的工作和所取得的成效。
With the requirment of precise seismic interpretation and thoroughgoing exploration, the conventional post-stack migration reveals its limitations. In order to solve these problems, the pre-stack depth migration is applied in seismic processing. This paper sums up the principle and technological process of pre-stack depth migration and gives several application examples in Jizhong area.
