Abstract:In high resolution processing,people often use statisticat wavelet deconvolution before stack and surface-consistent deconvolution,which play very effective roles in extracting surface-consistent informations and improving seismic data resolution.However,single-trace deconvolution is usually used in post stack data processing.In view of angular high fidelity,multi-trace or all-trace deconvolution after 2-D or 3-D stack will be very necessary.First the 3-D all wavelets relating to strata are obtained by making self-organized neurone clustering and fractal clustering,then the zero-phase homomorphic deconvolution after 3-D stack can be achievedsatisfactorily.As a result,the informations of abnormal geology body can be retamed,and seismic resolution improved successfully.
