Abstract:When using large offsets to acquire seismic data,the anisotropy in seismic wave propagation becomes a serious problem.By firstly analyzing concept and types of the anisotropy,the velocity characteristic of anisotropy,velocity analysis principle and application effects were studied in this paper,based on the analysis and studies,the anisotropic medium model was introduced,the exact estimation method for the anisotropic parameters was proposed,and then the method was utilized to conduct testing for field datasets.The comparison of testing results and routine velocity analysis results demonstrated obvious effects of the anisotropic velocity correction.
