FIELD: oil and gas production.
SUBSTANCE: procedure consists in supply of heat from exothermal reactions into zone of decomposition of gas hydrates and in withdrawal-extraction of precipitated hydrocarbon gas and liquid. According to the invention exothermal reactions are carried out beyond the zone of gas hydrate decomposition. Energy generated from exothermal reactions is converted to electric power by means of which there is facilitated decomposition of gas hydrates in one or several zones created in a reservoir-deposit of gas hydrates. High pressure heat carrier is heated for this purpose and is supplied into the deposit of gad hydrates for dynamic destruction of these hydrates. Also, high pressure heat carrier is supplied at distance in zone of gas hydrates decomposition from place of its input.
EFFECT: raised efficiency of gas extraction from gas hydrate deposits by increased and controlled yield, reduced power and capital expenditures, increased safety and ecological compatibility.
