| 摘 要： | 表面多次波是一种相干干扰，在海洋地球物理勘探中表面多次波尤为明显.本文给出了表面多次波衰减方法的研究现状的系统阐述，并分析了表面多次波衰减研究的发展趋势.表面多次波衰减主要有滤波法和波动理论方法.对于滤波法给出了广泛应用的抛物Radon变换法的实例，指出了抛物Radon 变换法存在滤波时能量泄漏的问题.同时本文分析了基于波动理论的处理优势和存在的问题，该方法可以处理任意介质的情形，但是对于数据的采集要求比较严格，另外在进行表面多次波衰减处理以前，要进行一系列的预处理，这些预处理的误差直接决定着多次波衰减的效果.最后，本文给出了表面多次波衰减的发展趋势——将滤波法和波动理论法结合来实现多次波的衰减.两类方法如何有效地结合是该类方法一个重要的研究方向.

| Abstract: | Surface-related multiple(SRM) is a coherent noise with strong energy especially in marine seismic data.The research progress in SRM attenuation is presented in this paper,and also the SRM future research direction.Methods that attenuate SRM can be classified into two categories: filter approach and wave equation-based method.An example of parabolic Radon transform(PRT) is demonstrated in this paper for filter approach,the energy leakage is a problem in traditional PRT. At the same time the advantages and shortcomings is analyzed for wave equation method,the SRM attenuation in this category has no assumptions about the subsurface,but the demands are strictly for data acquision.The SRM attenuation result of wave equation based method is decided by a series of preprocessing error.Combining filter and wave equation approach is the main future research topic,how to combine those two methods effectively is a problem should be paid more attenuation. |
