STORAGE OF NATURAL GAS in underground reservoirs, construction in the permafrost

摘要

Method of storing natural gas in an underground cavern created in the array permafrost rocks comprising injection of natural gas into a sealed cavity in the well, connecting the cavern with the earth's surface, storage injected gas at constant pressure for a predetermined period of time and subsequent selection of the stored gas through the well for supplying gas to the consumers, characterized in that in order to reduce the required pressure for the storage of natural gas by converting it into the form of gas hydrates under the natural th temperature surrounding the frozen rocks and corresponding reduction in the minimum penetration into the cavity accommodating an array of pre-constructing a sealed cavity at a depth not less than, for example, 60 m above the ground with a permissible pressure inside the cavity is not less than 10 kg / cm; in the cavity is lowered to the bottom of workstring suspension for injecting a pressurized gas via dispersing distributing feed gas substantially evenly over the area of ​​the bottom of the cavity; in the cavity is lowered to the bottom of workstring suspended for displacement on the liquid surface from the bottom; in the cavity is lowered, for example, on a cable-rope until the middle of its height audio frequency vibrator and a temperature sensor; cavity filled with 0.8 of its total capacity kriogidratnoy water mixture of 20 volume percent saline, e.g., sea water and 80% of such a frozen water ice or granular melkodroblenogo whose melting temperature substantially close to the average height of the cavity filled portion enclosing natural temperature of frozen rocks, for example, -3 ° C, prich
