Relative amplitude of seismic data processing research is a complicated system engineering.The authors analyzed the key to evaluating the deconvolution and relative amplitude compensation in practical seismic data processing flow,and pointed out that Yu wavelet statistical deconvolution has better predictive deconvolution in relative amplitude,and that residual amplitude compensation needs to use prestack elastic impedance or post-stack inversion results to verify relative amplitude of residual amplitude compensation.According to the principle of relative amplitude,the relative amplitude of seismic data are processed in the target area,and then pre-stack elastic parameters inversion is used to forecast the oil-gas possibility.The prediction result is consistent with the drilling result,thus demonstrating that the relative amplitude flow and methods have good application prospect.
