Khasanov, N. Musakaev, I. Gimaltdinov] We have investigated the features of the decomposition of gas hydrates into the gas and ice in the process of gas extraction from a porous medium saturated with the gas and the gas hydrate in the initial state. We have obtained selfsimilar solutions of this problem in an axisymmetric formulation describing the distributions of the main parameters in the stratum upon decomposition of the gas hydrate in an extended region. Critical diagrams of existence of the above solution have been constructed. It has been shown that in the case of a negative temperature of the stratum in the initial state (T 0 < 273.15 K), the gas hydrate will always decompose into the gas and ice. At a positive initial temperature of the stratum (T 0 > 273.15 K), the gas hydrate can decompose depending on the initial parameters of the system and the intensity of extraction of the gas with the formation of both water and ice.
