摘要
多次波衰减是地震资料处理中的一个难题。经过不懈研究,地球物理学家提出了多种压制多次波的方法。归纳起来主要有两种处理思路:①基于有效波与多次波的速度、频率、周期性存在差异的滤波法;②基于波动理论的预测减去法。介绍了基于两种思路的6种常用的多次波压制方法,探讨了方法的适用性。
Suppression of multiple waves attenuation is a difficult problem in seismic data processing. By hard working, geophysicists have developed many methods to treat multiple attenuation, and all the methods can he induced to two main thoughts for dealing with the multiple prolalems. 1) The filter method based on the difference between the effective wave and multiple wave, such as velocity, frequency and cyclicity;2) Multiple prediction and subtraction method based on wave theory. Six kinds of multiple attenuation methods in common use are introduced and the applicability of those methods is also discussed in this paper.
