Abstract:From analyzing the characters of marine seis-mic data, the paper considered it should pay moreattention to the following issues for marine seismicdata processing:wavelet processing and modifica-tion, application of deconvolution technique, sup-pression of multiple, velocity analysis of longspread data, residual static corrections and bin-sizeuniformization of 3-D data. On that basis, the pa-per emphatically discussed wavelet processing andmultiple-suppressed technique. There are two situ-ations for wavelet processing:the one is deconvo-lution by using far-field wavelet to detect inversewavelet in a condition that the far-field wavelet canbe provided in the field, so that the influence ofseismograph response, ghost reflection and bubblecan be better removed from seismic data;the sec-and is to directly detect the seismic wavelet fromraw seismic data when failing to acquire the wave-let signal at far field, using the inverse of the wave-let to compute the inverse wavelet, which can re-sult in good deconvolution results. As concerns thesuppression of marine multiple, there are many bet-ter approaches to be selected, the key is to analyzethe characters of the multiple in the region and se-lect purposefully the multiple-suppressed approa-ches.
