METHOD FOR DEVELOPMENT OF GAS-CONDENSATE FIELD Russian patent published in 1994 - IPC

FIELD: gas and oil producing industry. SUBSTANCE: during exploration of the field, presence of region with maximum content of condensate is determined. Field is drilled out with wells for injection of dry hydrocarbon gas. These wells are located in the region of maximum content of condensate at outline of gas pool. Field is also drilled with wells for withdrawal of condensate gas which are located up-dip. Raised part with minimum condensate content is drilled with additional rows of wells through which formation gas is withdraw. Dried gas from these wells is injected back into field. In course of development, content of hydrocarbons of products of producing wells is monitored. After fraction content is equalized, the field is operate as pure one in regime of depletion of formation energy. For this purpose, all wells are changed over for gas recovery. EFFECT: higher efficiency. 4 cl, 3 dwg
