地震波逆时偏移方法研究综述
|
摘要
地震波逆时偏移是目前精度较高的深度域成像方法,不同学者从不同的角度对逆时偏移方法进行了研究。因此,在回顾地震波逆时偏移方法发展历程的基础上,概述了当前流行的几种叠前、叠后逆时成像方法及其适用性,通过模型实例分析了几种叠后逆时成像方法存在的一些问题,同时对比了几种叠前逆时成像方法对Marm-ousi模型的逆时成像效果,最后指出了逆时偏移方法的发展方向。
Seismic reverse time migration is a method of high imaging precision in depth domain.Different realizations of reverse migration have been put forward.This paper reviewed the history of seismic reverse time migration,and summarized several prevalent prestack and poststack reverse time migration schemes and their adaptability.We demonstrated different poststack reverse time imaging conditions with model data,and compared the results from different reverse time migration methods on Marmousi model.The outlook of reverse time migration was also forecast.
