摘要：The idea of matched filtering in a sample-by-sample way is applied to prestack AVA inversion and an automatic method for reflection interfaces picking is proposed, which permits to transform the nonlinear prestack inversion into a two-step linear inversion. First, the residuals corresponding to all samples are calculated sample-by-sample. Then reflection interfaces are located automatically by picking up the troughs on the residual curve. Finally, the intercepts and gradients are estimated with the least-squares inversion in the frequency domain. Compared with the traditional methods to simultaneously invert for locations and amplitudes of reflections, the proposed method has higher computation efficiency and better stability and does not need some prior constraints such as the distribution or the number of the parameters. Synthetic examples and experiments on field data validate the feasibility of this method.
