一、前言从噪音和多种干扰背景中,识别和突出一次波,压制各种干扰波(如多次波等),一直是地震勘探中的一个关键问题。为了解决这个问题,近年发展起来的,而且比较成熟的方法,是采用多次迭加和各种数字处理技术。但是,所有这些手段,都必须要求有可靠的速度参数,才能收到预期的效果。 I. Preface It is always a key issue in seismic exploration to identify and highlight primary waves and suppress various interference waves (such as multiple waves) from the background of noises and multiple disturbances. In order to solve this problem, developed in recent years, and more mature method is to use multiple superimposed and various digital processing techniques. However, all of these tools must require reliable speed parameters in order to receive the desired results.
