摘　　要：本文回顾了多次波衰减方法的研究现状和进展,分析并指出了各种多次波衰减方法的优缺点.多次波衰减方法大致可以分为两类:基于信号分析的滤波类方法和基于波动方程的预测减去法.本文重点介绍了基于波动方程的多次波衰减方法,对比分析了波场延拓法、反馈迭代法和逆散射级数法三种基于波动方程多次波衰减方法的特点,并以模型和实例证明了反馈迭代法多次波衰减的效果.This paper reviews the progress of the research on the multiple attenuation method and analyses and points out the virtue and shortcoming of various multiple attenuation methods. The method of multiple attenuation can he classified into the filter method based on the signal analysis and wavefield prediction and subtraction based on the wave-equation method. The paper focuses on introducing the multiple attenuaton method based on the wave equation and compares the characters of wavefield extrapolation; iterative inversion method; and inverse scattering series and shows the effect of the iterative inversion method through some models and field seismic data.
