Anisotropic converted wave amplitude-preserving prestack time migration by the pseudo-offset method

Zhang Liyan Liu Yang CNPC Key Lab of Geophysical Exploration,China University of Petroleum,Beijing 102249,China.  
In this paper,we use the method of pseudo-offset migration(POM)to complete converted wave pre-stack time migration with amplitude-preservation in an anisotropic medium.The method maps the original traces into common conversion scatter point (CCSP)gathers directly by POM,which simplifies the conventional processing procedure for converted waves.The POM gather fold and SNR are high,which is favorable for velocity analysis and especially suitable for seismic data with low SNR.We used equivalent anisotropic theory to compute anisotropic parameters.Based on the scattering wave travel- time equation in a VTI medium,the POM pseudo-offset migration in anisotropic media was deduced.By amplitude-preserving POM gather mapping,velocity analysis,stack processing,and so on,the anisotropic migration results were acquired.The forward modeling computation and actual data processing demonstrate the validity of converted wave pre-stack time migration with amplitude-preservation using the anisotropic POM method.
