METHOD OF NATURAL GAS PRODUCTION FROM HYDRATES Russian patent published in 2017 - IPC E21B43/22 C09K8/52 

FIELD: gas industry.

SUBSTANCE: invention relates to gas production industry, in particular to methods of gas deposits development from natural hydrates deposits. According to method performing deposit drilling by wells with hydrates formation opening. After that, performing primary agent in form of thermodynamic hydrates formation inhibitor pumping into well with provision of methane hydrates stability equilibrium parameters under thermobaric formation conditions shift into hydrates resistance reduction area. At that, also performing secondary agent pumping, capable of carbon dioxide hydrate forming under thermobaric formation conditions at degree of hydrates formation inhibitor initial concentration dilution with hydrated water of not more than 10 times. Performing developed product extraction. At considerable distance between wells primary and secondary agents are pumped simultaneously. At small distance between wells said agents are pumped in series.

EFFECT: technical result is increase in methane extracting rate from hydrates and methane hydrate into free gas conversion degree.
