英文摘要：

Considering the complexity of subsurface medium, two-phase anisotropic model can veritably reflect the actual medium characteristics. Based on BISQ mechanism, this article derives the dispersion equation of 3D two-phase anisotropic medium, and gives the wave-number equation and expression used to derive phase velocity and 1/Q. Then we investigate the effects of the solid skeleton anisotropy, the solid/fluid coupling anisotropy and permeability anisotropy on attenuation and dispersion, and also make analysis of the azimuth characteristics of attenuation and dispersion. All of these studies can provide powerful theoretical criteria for predicting the existence and distribution of fluid in reservoir and the pore structure, and make multi-azimuth joint inversion for reservoir geophysical parameters be feasible.
