Based on this s-wave splitting theory, calculate the energy ratio of the radial and tangential components of the wide-azimuth ps-wave, which can predict the fractures of underground. On this basis, achieves a s-wave splitting analysis technique of multi-layer stripping of fractured medium. Firstly, using energy ratio calculates the azimuth of the first layer of fractured media, to get the fast and slow shear wave time difference, and other fracture parameters; and then the time difference is applied to the slow-wave compensation, finally, the fast s-wave and compensated slow s-wave will be rotated back to the original on the radial and tangential components. After that the first anisotropic media layer is changed into isotropic media, and so on, step by step, get the multi-layer medium anisotropic parameters, by analyzing s-wave splitting of each layer.
