COMPLEX FOR EXTRACTION OF HYDROCARBON CONTAINING FLUID FROM HYDROCARBON DEPOSIT Russian patent published in 2021 - IPC E21B43/16 F25J3/08 B01D53/00 

FIELD: fluid containing hydrocarbons production.

SUBSTANCE: complex is claimed for the production of a fluid containing hydrocarbons from a hydrocarbon reservoir. The complex for the production of a fluid containing hydrocarbons from a hydrocarbon deposit includes a power plant, a carbon dioxide plant, a liquefaction device and an injection device. The power plant contains an internal combustion engine, which is provided with the possibility of supplying gas separated from the fluid containing hydrocarbons. The internal combustion engine is configured to operate by burning gas separated from the hydrocarbon containing fluid with air. The internal combustion engine is configured to form a compressed air-gas mixture containing air and gas separated from the hydrocarbon-containing fluid. The internal combustion engine is configured to form said compressed air-gas mixture prior to said combustion. The possibility of exhaust gases from the internal combustion engine is provided. The carbon dioxide plant is configured to extract the carbon dioxide-containing exhaust gas component from the exhaust gases. The liquefaction device is configured to liquefy at least a portion of the carbon dioxide-containing component to produce liquefied carbon dioxide. The injection device is configured to inject liquefied carbon dioxide into the hydrocarbon reservoir through at least one well.

EFFECT: increased oil recovery in the development of oil fields and increased condensate recovery in the development of gas condensate fields, reduced energy costs for the injection process, increased generated power and increased the amount of energy generated.
