Abstract

A method of recycling carbon dioxide in marine gas hydrate deposits includes well-drilling in seabed, pumping carbon dioxide into the well under pressure, which is higher than in existing gas hydrate reservoir, pumping out methane gas, preliminary determination of level, temperature and pressure of a gas hydrate bed. After well drilling is conducted density gamma-gamma logging of the gas hydrate deposit followed by determination of the exact level of the gas hydrate bed, perforation of an outer tube of well. In the well water is pumped under pressure exceeding the reservoir pressure in the natural gas hydrate reservoir, up to formation of a crack of rupture in the natural gas hydrate reservoir on the working level – hydraulic fracturing, carbon dioxide is injected into the well under the temperature exceeding by 1- the temperature of gas hydrate formation followed by another density gamma-gamma logging of the gas hydrate deposit. Then the level and limit of replacement of gas hydrate of methane by gas hydrates of carbon dioxide is defined and followed by another perforation of the outer tube and another hydraulic fracturing on the interface of gas hydrate of carbon dioxide and gas hydrate of methane located higher, while the well is drilled up to the base of gas hydrate reservoir.
