| Abstract: | By using optimal amplitude variation with offset(AVO) linear approximation formula based on rock physics model,the reflection coefficient approximation formula which satisfies the accuracy in the condition of near critical angle incidence was constructed.On the assumption of seismic convolution theory,the inversion object function for the optimal coefficients was derived by the solution estimation method of Bayesian maximum posterior probability density.Lame parameters were sensitive to the underground rese... |
