For contact-cemented gas hydrate layer, the elastic parameters most sensitive to change of saturation are S-wave velocity and wave impedance; For non-contact cemented gas hydrate layer, the elastic parameters most sensitive to change of saturation are ratio of elastic module and P-w.
对于接触胶结水合物层来说,对饱和度变化最为敏感的弹性参数是横波速度和横波波阻抗;对于非接触胶结水合物层来说,对饱和度变化最为敏感的参数是弹性模量比和纵波速度;对于游离气层来说,对饱和度变化最为敏感的弹性参数是弹性模量比和泊松比。
