Abstract

This invention discloses a CCUS-EOR system coupled with new energy sources, belonging to the field of carbon emission technology. The CCUS-EOR system of this invention includes a carbon storage module connected to a multiphase injection module, which in turn is connected to a recirculating gas treatment module. The recirculating gas treatment module is connected to a new energy module, which is also connected to the multiphase injection module. This CCUS-EOR system, by using a new energy module to supply power and heat to the CCUS-EOR process unit and employing a fully enclosed process to ensure no CO2 leakage, achieves zero carbon emissions from the process unit, solving the problem of high carbon emissions caused by the large-scale consumption of fossil fuels in conventional CCUS-EOR process units.
