In the process of gas hydrates exploration, the gas hydrate occurrence state is the key factor to determine the exploiting method. In this paper, we find a way to identify gas hydrate occurrence states by seismic P-wave attenuation. We find that the P-wave attenuation characteristics are different between the pore-filling hydrate-bearing sediments and the fracture-filling hydratebearing sediments. The attenuation is prominent in fracture-filling hydrate-bearing sediments. However, the pore-filling hydratebearing sediments have week attenuation effect. We use this difference to identify the gas hydrate occurrences state and apply it in northern South China Sea. The results depict that the P-wave attenuation is an effective attribute to identify gas hydrate occurrence states, which lays a foundation for the identification of gas hydrate occurrence state by seismic P-wave attenuation.
