“…Silicone polymers, fluoropolymers and alkanes polymers have achieved the thickening effect [21][22][23][24]. However, low molecular weight alkanes polymers, including poly (vinyl ethyl ether) (PVEE) and poly-1-decene (P1D), it has a little CO 2 thickening [25,26]. However, direct CO 2 thickening technology also faces significant challenges.…”

In the heterogeneous reservoirs, CO 2 flooding easily leads to CO 2 gas channeling, which can seriously affect sweeping efficiency and reduce oil recovery. After thoroughly investigating the advantages and shortcomings of various CO 2 plugging technologies, this paper focuses on the feasibility of improving conventional wateralternating gas (WAG) through CO 2 -responsive gel materials. Based on the different chemical reaction mechanisms between the unique chemical structure and CO 2 , changes in the material's physical and chemical properties can respond to CO 2 . The feasibility of utilizing these property changes for CO 2 -responsive plugging is explored. Various CO 2 -responsive gels and gel nanoparticles have been extensively researched in different fields, such as energy, medicine, and biology. This paper surveys the molecular structures, chemical compositions, response mechanisms, and changes of these CO 2 -responsive gels, aiming to draw insights into the carbon dioxide-enhanced oil recovery (CO 2 -EOR) field. Finally, the key issues and future development direction of CO 2 -responsive plugging gels were analyzed. KEYWORDSGas channeling; sweep efficiency; CO 2 -responsive gel; CO 2 -EOR
