The relationship of VTI media P-SV wave converted Point and anisotropy parameters

LI Tian-cheng1,2,NIU Bin-hua1,SUN Chun-yan3,LIU Guo-qing4(1.School of Geophysics and information Technology,China University of Geosciences,Beijing 100083,China;2.China Non-Ferrous Metals Resource Geological Survey Center,Beijing 100012,China;3.School of Engineering Technology,China University of Geosciences,Beijing 100083,Chian; 4Henan Non-Ferrous Metals Geological Survey Department,5th Crew,Zhengzhou 450042,China)  
The paper shows anisotropy effect on the conversion position and evaluate the error introduced in data processing due to neglecting anisotropy.It is demonstrated that the location of the conversion point depends strongly on elastic properties of the media.The paper introduces also the improved equations for calculating the conversion point of the P-SV converted wave(C-wave) in VTI media.The introduced equations for the conversion point are valid for offset about three-times the reflector depth.The equation reveal some addition analytical insights into the converted wave properties.
