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).

It can be seen that mercury contents in sulfides of the density fractions are different from each other in the same coal, which implied that mercury is distributed in sulfide unhomogeneously. The reasons of the unhomogeneity of mercury distribution in sulfide may be that mercury exist in sulfide in form of submicrometer size individual mineral such as cinnabar, and not in form of solid solution in pyrite, or that in coal, there are multi-stage and multi-origin sulfides among which the distribution and modes of mercury are different from each other.
