Abstract

the imaging quality of C-wave data, and shear-wave splitting analysis and compensation (SSAC) is a key step in the data processing workflows. The overburden shear-wave splitting effects of HTI layers should be removed for the analysis and compensation of the target layer in the situation of multiple HTI layers. The layer-stripping method is one of the best means for SSAC. Here, we establish a workflow and implemented SSAC for C-wave analysis and processing based on the layer stripping method using a numerical modeling dataset. There are seven layers in the model including three HTI layers. The modeling dataset is obtained with full wavefield information using the reflectivity method. The workflow of analysis for azimuthal anisotropy correction includes: ① Computing the fast (S1) and slow (S2) shear-wave component using a windowed layer stripping shear-wave splitting method based on the radial (R-component) and transverse (T-component) data; ② Picking the fast polarization direction angle, and the time delay of S1 and S2 using a scanning spectrum; ③ Correcting the R- and T-component seismic sections using the compensated fast polarization direction angle and the time delay between S1 and S2.
