摘要

A method for production of gas methane from offshore gas-hydrate deposits includes well drilling in sea ground, pumping in of carbon dioxide gas, pumping out of gas methane. Preliminarily one determines height of the gas-hydrate bed, and its pressure and temperature. After that one drills a well lower than the level of bedding of the layer developed, with pumping in carbon dioxide gas to the well under pressure that exceeds existing pressure in the gas hydrate deposit, with temperature corresponding to the temperature of the gas-hydrate deposit.
