介绍了利用多道反射地震资料，采用反射振幅随炮检距变化AVO(Amplitude versus Offset)技术和其他地震正、反演方法，通过研究地震剖面上的拟海底反射层(BSR)分布、地震弹性参数特征，来探讨BSR上、下方含天然气水合物沉积层和含游离气沉积层的内部结构和某些主要物理性质，如沉积物的空隙率、天然气水合物的饱和度等，由此来评估海底天然气水合物的资源前景并研究其成矿机制。

This paper introduces some methods of studying marine gas hydrate using multi-channel reflection seismic data, such as AVO (Amplitude Versus Offset) analysis and other forward modeling and inversion of seismic data. Through studying the BSR (Bottom Simulating Reflection) characters and the elastic parametric structure of gas hydrate deposits, we can get the internal structure and some physical attributes of the hydrate-bearing sediments above the BSR and the sediments containing free gas below the BSR, such as the porosity of the sediments and the saturation of gas hydrate, then evaluate the amounts of the gas hydrate and discuss its formation mechanism.
