Both the temperature and pressure are key parameters to keep natural gas hydrate as solid. Based on thermal physical mechanics and the characteristic property of ideal gas, and by computer simulating the decomposition of methane hydrates and carbon dioxide hydrates under different temperature (all above 0 ℃) and pressure conditions, the P-T balance station of methane hydrate dissociation was obtained and the relationship between temperature and pressure for land gas hydrate sampling was discussed.
