HYDROCARBON EXTRACTION SYSTEM Russian patent published in 2021 - IPC E21B43/16 

FIELD: oil, gas and coke-chemical industries.

SUBSTANCE: invention relates to oil and gas industry and can be used in production of hydrocarbons, for example, from oil deposits, gas-oil deposits, oil and gas deposits, gas condensate deposits, oil and gas condensate deposits, gas deposits. Complex for hydrocarbon production includes power-generating plant and pumping device. Power-driven power plant comprises gas engine or gas turbine engine. Any of said engines is configured to combust gas separated from fluid extracted from deposit using air as oxidant. Any of said engines is configured to form compressed gas-air mixture containing air and gas used as oxidizer separated from fluid extracted from deposit. Any of said engines is configured to form compressed gas-air mixture prior to combustion. Complex contains a carbon dioxide plant. It is made with possibility to obtain gas containing carbon dioxide and/or liquid containing carbon dioxide from exhaust gases of power plant. Pumping device is configured to pump gas containing carbon dioxide and/or a liquid containing carbon dioxide into the deposit through at least one well.

EFFECT: technical result is increased return of deposit and increased amount of generated energy.
