METHOD gas condensate field development of gas-bearing HIGH FLOOR OF cycling process

摘要

FIELD: oil and gas production.;SUBSTANCE: procedure consists in opening upper section of near-top zone of gas deposit with pressure wells, in exposure of lower section of periphery zone of gas deposit with producers, in implementing cycling process by means of pumping dry gas through pressure wells and in simultaneous withdrawal of gas-condensate mixture though producers. According to the invention exposure of the gas deposit is performed with horizontal pressure wells and horizontal producers by perforation of horizontal boreholes of wells. Also, pressure wells and producers are drilled to facilitate maximal distance between intervals of perforation of pressure wells and producers. Upon completion of cycling process a lower section of the gas deposit is exposed with pressure wells and gas-condensate mixture is withdrawn in pressure wells from a lower section of the gas deposit.;EFFECT: raised sweep factor and increased coefficient of condensate extraction from gas deposit at development of gas condensate deposit with big gas column implementing cycling process.;2 cl, 4 dwg
