Method for Wavelet Function Selection During SurfaceWave Attenuation Processing

doi:10.7657/XJPG20160416

Abstract

Abstract: Based on the discussions on the principles of surface wave attenuation processing in wavelet domain, it is concluded that good separability of wavelet decomposition result is needed during surface wave attenuation processing. Because support length decides local features and vanishing moment decides the energy concentration degree of low?frequency and low?wave?number components, a symmetrical wavelet function principle that short support length and high vanishing moment should be chosen is determined, and Symmlet wavelet function is considered as the optimal wavelet. Surface?wave attenuation degree and influence of reflection wave are analyzed regarding surfacewave attenuation processing results obtained from actual seismic data and synthetic seismogram, which validates the method for wavelet function selection
