The extrapolated multi-component wavefields contain both compressional waves and shear waves.Whether these two wave modes can be separated from the wavefields makes differences for isotropic and anisotropic elastic reverse time migration.The separation methods based on divergence and curl operators only perform perfectly in isotropic media,whereas do not work well in anisotropic medium.On the basis of elastic wave numerical simulation scheme of irregular and unstructured grids,a wave-mode separation approach which is suitable for anisotropic media is developed.This method firstly extracts the relationship between the phase angle and polarizing angle by solving the Christoffel equation,then directly obtains the relationship between group angle and polarizing angle through bridging group angle and phase angle.Compared with the existing methods,the computational efficiency of this producer is improved with a small storage capacity.By testing the simple anisotropicmodels and SEG anisotropic Hess model,thevalidity of our scheme proposed in this paper is proved.
