Both splitting of converted shear wave and directionality of fast wave polarization can hardly be modeled by isotropy and horizontal transverse isotropic propagation.
Transverse isotropic model for HTI media with a horizontal symmetry axis is the simplest one used to describe the transverse isotropy of the fractured reservoirs containing parallel vertical cracks.
Basing on former researcher findings, simplified and deduced the formulas of formation deflecting force and azimuth force of transverse isotropy formation under the condition of the anisotropy bit.
According to the results, during of the axisymmetry deformation, longitudinal anisotropy and transversal isotropy of polycrystal were obvious with the effective strain increasing.
