In this paper the processes of formation and decomposition of natural gas hydrates in wet salted sand samples were studied. Investigations of phase transitions were performed on a specially assembled DTA installation. It is shown that with decrease of the humidity and increase of the salinity of media the degree of supercooling decreases, and the amount of the gas bound to hydrate decreases. It has been found that in comparison with the water-gas system in dispersed rocks there is a shift of thermobaric conditions of hydrate formation to the area of high pressures and low temperatures.
