英文摘要Numerical results demonstrate that the one-way wave equation modeling scheme exhibits sufficient accuracy in terms of primary reflected waves in comparison with the two-way wave equation scheme. The computational cost is greatly reduced by employing the one-way wave equation scheme. Moreover, only a rough velocity model is needed for implementing the one-way wave equation scheme in seismic modeling. Since the one-way wave equation modeling scheme can be considered as the inverse depth migration, we can use the current depth migration schemes and its codes. Accounting for both accuracy and computational efficiency, we use the explicit short extrapolation operator scheme in a complicated medium layer and the split step Fourier operators in a simple medium layer during depth extrapolations. Reflected coefficients are obtained by accounting for its variation with incident angles in the scheme.
