The study of the anisotropy of the subsurface media is a challenging task during exploration and development of oil and gas, and the development of the fractured fields with S-wave data has become a heated topic. This paper has tentatively reviewed and discussed the anisotropy of the subsurface rocks in four structures in Yinggehai basin based on the multiwave seismic data acquired during the first multiwave seismic survey on offshore China seas, and reached some significant conclusions.
