地震资料多次波处理

MULTIPLE ATTENUATION IN SEISMIC DATA PROCESSING

对于多次波压制,前人做了很多工作,并已开发了多种多次波压制技术。在实际工作中,合理地选取压制多次波的方法,是获得高品质的地震剖面关键。不幸的是,并不存在最优的多次波压制技术可以适用于所有情况。有些情况下,简单的常规多次波压制方法反而能获得更好的效果。本文分析了不同类型多次波压制方法的优劣;同时,笔者利用几种多次波压制方法的优化组合,获得令人满意的多次波压制结果。

Many researches have been conducted on multiple-suppression techniques. Geophysicists have attained great achievements in those researches. It is essential for high- quality seismic section to choose proper multiple-attenuation solutions. Unfortunately, there is no best demultiple technique that works everywhere. In some instances, simpler conventional techniques yield better results than sophisticated ones. Our purpose is to present advantages and weaknesses of different multiple-attenuation techniques, which is helpful for our optimum combination of some chosen demultiple techniques.
