In combination with seismic reflection features and probable gas resource discussion, it is concluded that there probably exist two kinds of reservoir models in the X Block. In the areas where faults or collapse structures develop, the gas resource is probably composed of thermogenic gas, gas hydrate is characterized by multilayer distribution, while in the inactive areas the gas resource is probably composed of biogenic gas, and gas hydrate is characterized by monolayer, which mainly distributes in a narrow zone on the surface of BSR (bottom-simulating seismic reflector).

结合地震反射特征和可能的气源讨论初步认为，X区块天然气水合物的成藏模式主要有两种类型：在断裂或滑塌构造发育区，水合物的气源以热解成因气为主，水合物呈多层分布；在构造平缓地区，水合物的气源以生物成因气为主，水合物呈单层分布，且主要分布在似海底反射之上一个狭窄的范围内。
