Abstract

In this work, the kinetic parameters and equilibrium conditions of the formation of natural gas hydrates in moist fresh and saline sand samples were studied by the method of differential thermal analysis. It was found that, in comparison with the systems "water-natural gas" and "sodium chloride solution-natural gas" in dispersed rocks, the equilibrium curves of hydrate formation are shifted to the region of high pressures and low temperatures. It is shown that the salinity of the pore solution leads to a decrease in the amount of absorbed gas and a decrease in the rate of hydrate formation.
