摘要：In order to investigate the conditions of formation and dissociation of natural gas hydrates, a set of experimental device was developed to measure the effect of pore size, salinity on the phase equilibrium condition of methane hydrates using constant volume method. The experimental results indicate that formation of methane hydrate in porous media is easier than that in pure-water, and the induction time decreases. Equilibrium curves move to the right as pore size increases, while the increase of salinity makes the curve moving to the left. The influence of porosity and salinity on phase equilibrium point of hydrates is different. This study will give some valuable thermodynamic data for the formation and stability of natural gas hydrates in sediments.
