递进式多次波衰减技术在海洋地震资料中的应用

Application of progressive multiple attenuation technique in marine seismic data

多次波是海洋地震处理中的主要噪声,多次波衰减是海洋地震资料处理中的重要环节之一。针对不同多次波类型,相应采用的方法也不同。在分析海洋资料多次波类型的基础上,针对不同特征,选取合理方法,进行有效组合。通过实际资料的试验,形成一套有效的、适用于海洋地震资料的递进式多次波衰减流程。

The multiple attenuation is one of the important links in marine seismic data processing as it is the main noise in marine seismic data. The different methods are used for the different types of multiples. Based on the analysis of the types of the multiple in the marine seismic data, the suitable methods are selected to make effective combination according to different characteristics of the multiple. A set of effective and suitable processing workflow for the attenuation of the multiple in the marine seismic data is developed through the tests of real data.
