Abstract
The processes of formation and decomposition of natural gas hydrates of the Srednevilyuiskiy and Otradninskiy gas condensate fields of Yakutia in model solutions of the sodium hydrocarbonate type have been studied. It was found that with an increase in the concentration of solutions, the volumes of gases bound into the hydrate decrease, and the composition of gas affects the decomposition of the obtained hydrates. It is shown that with an increase in the molar mass of natural gas, the rates of hydrate decomposition decrease.
