英文摘要	Gas hydrate formation conditions and its fraction out of pore space are two important issues. Based on theoretical gas hydrate thermo-dynamic model, semi-quantitative analyses on various intrinsic factors (such as temperature, pressure, gas composition, pore-water salinity, sediment pore size) affecting gas hydrate formation conditions and its fraction out of pore space are conducted. The analytical results indicate that gas composition (e. g., the mixture of methane and propane) plays a significant role in affecting gas hydrate formation conditions of temperature and pressure; pore-water salinity also greatly affects gas hydrate formation conditions; sediment pore size within a small range (1 x 10(-6) similar to 4 x 10(-8) m) have a small effect on gas hydrate formation conditions. Gas hydrate fraction out of pore space is little affected by pore size and pore-water salinity, but is strongly dependent on gas supply.
