METHOD OF SETTING UP AND OPERATION OF UNDERGROUND GAS STORAGE IN OIL-GAS CONDENSATE DEPOSITS

摘要

FIELD: gas and oil producing industry; operation of underground gas storages on basis of depleted oil and oil-gas condensate deposits. SUBSTANCE: method includes gas injection and extraction through injection wells in pool roof part, and oil withdrawal through oil producing wells from reservoirs of pool bottom part. In this case, zones of maximum oil reserves are singled out and horizontal part of bore of oil producing wells in these zones are located with consideration of zones with the best permeability of reservoir and surface of gas-oil contact. Conditions of maximum distance of any point of bore horizontal part from bottom-holes of the nearest gas injection wells are to be observed. EFFECT: higher efficiency of oil recovery. 2 cl, 2 dwg
