Making the best use of the curvelet transform's strong local directional characteristics, seismic frequency bands are transformed into scale data with and without noise. Since surface waves and primary reflected waves have less overlap in the curvelet domain, we can effectively identify and separate noise. Applying this method to prestack seismic data can successfully remove surface waves and, at the same time, protect the reflected events well, particularly in the low-frequency band. This indicates that the method described in this paper is an effective and amplitude-preserving method. 收起<<
