PROCESS OF CONDENSATE RECOVERY RATE INCREASE

FIELD: mining. ^ SUBSTANCE: process involves gas-condensate filed development in the stratum energy depletion mode at the first stage and productive collector waterflooding at the second stage. The invention involves condensate rim formation above gas-water contact at the first stage at the bulk-type gas condensate field, with condensate saturation of productive collector pore space due to segregation process. A system of horizontal and/or vertical production and injection wells is drilled in the condensate rim, and in the pool of existing production wells horizontal and/or declined sidetracks are spudded to create production and injection wells. At that, water is pumped into injection wells in the productive collector soaking mode. For that the water is treated by a chemical reagent or injected together with gas, while condensate is recovered from production wells. ^ EFFECT: higher final condensate recovery from gas-condensate field of bulk type due to productive collector waterflooding and accounting for segregation process during long preceding depletion-mode development period. ^ 2 cl, 1 dwg, 1 ex
