A CCUS system for exploiting a thickened oil reservoir based on an optimal flue gas COenrichment ratio. The CCUS system comprises a flue gas COenrichment unit, a flue gas injection unit, a thickened oil thermal production well group unit and a produced gas recovery unit; the fuel gas COenrichment 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.
