Ways to reduce the anthropogenic impact on the environment during exploitation of gas fields and underground gas storage facilities

摘要

FIELD: oil-and-gas production.;SUBSTANCE: method includes construction of inclined-directed pressure-relief degasification wells. Pressure-relief degasification wells are implemented in the form of wells allowing U-shaped profile and out to the surface of ground. Depth of placement of horizontal parts increases depth of bedding of top permeable reservoir bed. U-shaped wells are located in the form of polygon, cased by slotted pipes string in its horizontal parts and are connected to each other into closed system, operating to total gas-collecting unit.;EFFECT: reduction of man's impact on environment at operation of natural gas field and underground gas storage.;3 dwg, 1 tbl
