According to characteristics of the seismic data from the low snr region with complex surface , this paper is started from solving the static correction problem and reasonable eliminating all kinds of disturbance in the seismic data from the low snr region with complex surface . through the whole process of seismic data processing which includes a series of processing methods that are suitable for the low snr region , namely , from the choosing of the floating base - level , the static correction in the field and indoors , the eliminating of all kinds of noise before and after stacking , the velocity analysis with high - resolution , the reasonable techniques of deconvolution before stacking and wavelet processing after stacking , to the method choosing of the high - resolution stacking and the reasonable and accurate offset imaging , a set of the complete and effective flow for processing seismic data from the low snr region with complex surface are finally formed , which can meet the need of explo 本文針對(duì)復(fù)雜地表低信噪比地區(qū)地震資料的特點(diǎn),以解決復(fù)雜地表低信噪比地區(qū)地震資料靜校正問題及合理剔除各類干擾為出發(fā)點(diǎn),在整個(gè)地震資料處理過程中,從浮動(dòng)基準(zhǔn)面的選取、野外及室內(nèi)靜校正、疊前疊后各類噪音的去除、高精度速度分析、合理的疊前反褶積及疊后子波處理技術(shù)、到選用高精度的疊加技術(shù)及合理準(zhǔn)確的偏移成像方法等一系列適合于復(fù)雜地表低信噪比地區(qū)的處理方法,最終形成一套較完整且有效的針對(duì)復(fù)雜地表低信噪比地區(qū)地震資料的處理流程。
