Features and controlling factors of BSR in Shenhu area, South China Sea

The high-resolution seismic reflection profiles from gas hydrate drilling zones of Shenhu area in South China Sea were interpreted precisely so as to analyze the features and the controlling factors of BSR (Bottom Simulating Reflector).It has been concluded that gas hydrate and BSR are closely related.In the study area,BSR is characterized by multi-axes and is discontinuous.The amplitude of BSR is mainly controlled by the free gas underneath the base of gas hydrate stable zone.BSR in Shenhu area might be influenced by the vertical combination of gas hydrates of different origins.
