Abstract:BISQ equation is a latest studied result which describes the propagation of seismic and acoustic waves in porous medium with fluid under common action of Biot-flow and squirt flow.Starting from the high frequency limited equation of BISQ equation in transversely isotropic porous medium,the paper numerically simulated the propagation in transversely isotropic porous medium by using staggered grid method.The results show that there exist fast quasi-P-wave,slow quasi-P-wave,quasi-SH-wave and quasi-SV-wave as well as also there appears the phenomenon of S-wave splitting and acute wave plane when elastic wave propagates in the transversely isotropic porous medium,which show the correctness of BISQ theory and laid the foundation of further applied study.
