摘要
A seismic wave modeling of two-phase media based on BISQ model is proposed in this paper.From the fundamental equations of BISQ model,the authors first derive the expression of a staggered grid and high-order finite difference method using the absorbing boundary of perfect matched layer(PML).Then the authors carry out a numerical modeling of seismic wave filed in the two-phase isotropic media.Finally the authors analyze impacts of parameter variation upon wave filed by adjusting the porosity and permeability parameters.The numerical modeling results show that the forward modeling based on BISQ model correctly reflect the wave field characteristics in two-phase isotropic media,and that the influences caused by the variation of model parameters on wave field are very obvious.
