Abstract: Focusing on amplitude?preserving processing, the authors establish a gather optimization processing procedure of actual seismic data to optimize pre?stack common?reflection?point (CRP) gathers, by which energy loss compensition can be made using inverse Q filtering, wavelet stretch distortion correction can be made by spectrum equilibrium, and residual moveout removing will be realized by waveform matching approach, and good effects have been gained after the optimized procedure was applied to AVO analysis of carbonate buriedhill reservoirs in Bohai Bay basin. This paper indicates that the optimized gather processing technology can better highlight the AVO response characteristics of subsurface strata
