FIELD: oil and gas industry. ^ SUBSTANCE: drilling and construction of wells (3, 4) is performed in the method by using pipes, threaded connectors, downhole equipment and annular space elements. The latter are protected against helium penetration by means of polymer coatings and leakproof materials. Production of one or several small deposits (2) of helium-containing natural gas is performed, then it is transported and pumped to large deposit (1) in the volume equal to or more by 1.2-1.3 times than total volume of helium contained in natural gas of the whole group of deposits. The above large deposit (1) is better as to gas deposits by one order and more than any of small deposits (2). Operation of large deposit (1), as well as pumping of helium or helium concentrate extracted at the works process plants (6) from produced helium-containing gas to small deposits (2) to be stored in structures free from natural gas is performed. ^ EFFECT: providing the possibility of production of natural gas irrespective of demand for helium, minimising the costs for construction of helium storage facility. ^ 1 dwg |
