Abstract：There are 30 years since the AVO processing method has been developed,sometimes up and sometimes down,but the application of the technology is wide and fast development in recent years.Comparing to other techniques,AVO method has an irreplaceable function in searching subtle reservoir and fractured reservoir.Through study of integrating processing into interpretation for Yangwu 3-D data,the paper discovered that VTI anisotropic medium has larger influence of time difference on NMO.This study successfully uses imaging theory of VTI medium to correct time difference of seismic data in that region.At the same time,using compensation for spherical spread and absorption in time-frequency domain and surface-consistent (for shot,receiver and offset) deconvolution can obtain a good compensating result in amplitude and frequency,which meets the demand for relatively reserving amplitude.Through this study of integrating processing into interpretation,a geologic anomaly body having second category of AVO character has been found,which is uncapable of distinction under conventional imaging condition.
