摘要

Based on the theory of self-adaptive pattern recognition and wave filtration, the suppressing approach of dispersion surface wave can effectively suppress the surface wave energy stacked with the frequency belts of positive signals. The actual processed data applied in Gulong fault sag demonstrate that the approach possesses much better amplitude preservation as well as can effectively suppress the noise before stack, so it is one of effective methods to preprocess before stack in Hi-Fi imaging of seismic data.
