摘要

Gas hydrate bearing zone are significantly affected by anisotropy in Shenhu area, South China Sea. The research takes the changing velocity field of sea water and anisotropic elastic parameters into account to models for simulation. Full-wave field forward simulation data with different saturation of gas hydrate has been generated. Anisotropy field separation method is used to provide more accurate seismic data of pp and ps waves. Study shows that anisotropy has a significant impact on multi-component AVA characteristics, the values of gradient and polarity reversal angle. In addition, multi component sweetness seismic attribute can be used as significant seismic attribute to identify gas hydrate reservoirs.
