DESIGNED MODELING OF TECHNOLOGIES FOR EXTRACTION OF DIFFICULTABLE LIQUID HYDROCARBONS FROM GAS CONDENSATE DEPOSITS OF OIL AND GAS CONDENSATE FIELDS IN VOLUME CONCENTRATIONS BELOW THRESHOLD OF FILTRATION

Abstract

The task of developing technologies aimed at extracting liquid hydrocarbons (reservoir oil and retrograde condensate) from the gas condensate part of gas condensate and oil and gas condensate fields is considered. Features of location and filtration of reservoir fluids in the capacitive volumes of gas-saturated productive layers of gas condensate and oil and gas condensate fields are shown. The results of computational modeling of production technologies for hard-to-recover reservoir liquid hydrocarbons are presented. The technology of cyclic pumping of the rims of a hydrocarbon solvent that is easily evaporated under conditions of the formation is considered.

Keywords: difficult-to-recover liquid hydrocarbons, filtration threshold, filtering capacitive volumes, structurally-clamped capacitive volumes, design simulation, cyclic pumping, injection cycles, solvents, dry gas, mixing displacement, final pumping of dry gas, technology efficiency, final stage, carbon dioxide.
