STUDY ON P,SV-WAVE FEATURES IN HOMOGENEOUS TRANSVERSELY ISOTROPIC MEDIA

MENG Qing sheng,HE Qiao deng, WANG De li (College of Geo-Exploration Science and Technology, Jilin University, Changchun 130026,China)  
The conventional reflection data processing is based on the assumption that the medium is homogeneous and isotropic. The anisotropy may seriously affect the result of processing and interpretation. This paper deals with the ray propagation in 2D homogeneous transversely isotropic medium and describes the features of anisotropic velocity wavefields. For the quasi P wave, the absolute values of ε and δ characterize the shape of wavefront, on the other hand, the difference of ε and δ characterizes the ray propagation; However, for quasi SV wave, σ is the main factor.
