  • CCUS (carbon capture utilization and storage) system for exploiting thickened oil reservoirs based on optimal flue gas COenrichment ratio and working method thereof
    Patent number: 11208872
    Abstract: A CCUS system for exploiting a thickened oil reservoir based on an optimal flue gas CO2 enrichment ratio. The CCUS system comprises a flue gas CO2 enrichment unit, a flue gas injection unit, a thickened oil thermal production well group unit and a produced gas recovery unit; the fuel gas CO2 enrichment unit comprises an air separating enrichment unit and a boiler injection gas premixed tank; the air separating enrichment unit comprises an air separating primary device used for separating air into oxygen and nitrogen preliminarily, and an air separating secondary device used for further enriching a part of the oxygen which is subjected to the preliminary separation; and the boiler injection gas premixed tank is used for mixing the preliminarily separated nitrogen, the preliminarily separated part of the oxygen and/or the further enriched oxygen.
