英文摘要	Considering the velocity anisotropy of the solid/fluid relative motion and employment of the BISQ theory([1]) based on the one-dimensional porous isotropic case, we establish a two-phase anisotropic elastic wave equation to simultaneously include the Blot and the squirt mechanisms in terms of both the basic principles of the fluid's mass conservation and the elastic-wave dynamical equations in the two-phase anisotropic rock. Numerical results, while the Blot-flow and the squirt-flow effects are simultaneously considered in the transversely isotropic (TI) poroelastic medium, show that the attenuation of the quasi P-wave and the quasi SV-wave strongly depend on the permeability anisotropy, and the attenuation behavior at low and high frequencies is contrary. Meanwhile, the attenuation and dispersion of the quasi P-wave are also affected seriously by the anisotropic solid/fluid coupling additional density.
