      Abstract
    • The research of multiple suppression and analysis of influence of multiple amplitude upon primary amplitude-via-offset (AVO) need an effective multiple-modeling method. Thus, a new method has been developed that can automatically calculate multiple ray codes in any complex stratified media, making multiple ray trace fast. Meanwhile, an approach to the computation of multiple amplitude by methods of seeking table and interpolation are discussed. The modeling result shows that the method is of high precision and fast-speed in multiple amplitude calculation. The maximum relative error of amplitude is 1.8% and the spent time by using the method has decreased by 0.4 times one by using accurate ray tracing in the designed model.
