Abstract: Focusing on the theories and technologies of chemical flooding for enhanced oil recovery (EOR) as the core research subject, this study systematically analyzes the technological innovation mechanisms and field implementation patterns in oil and gas field development, clarifies the implementation pathways and fundamental insights, and points out the future directions for EOR technological innovation. The study elaborates on the synergistic mechanisms of oil displacement agents for high-temperature and high-salinity reservoirs, alongside the innovation and development histories of alkali-free binary composite flooding and heterogeneous composite flooding technologies. The study demonstrates that EOR innovation follows a defined pathway:basic theoretical research→single-well trial injection (production)→well-group pilot test→expanded section pilot→industrial application. Technological development should be driven by theoretical innovation, conform to first principles, undergo continuous iteration and refinement, and broaden its application domains. The future innovation directions for oil and gas development technologies are identified. Efforts should be focused on tackling key technologies:new chemical/engineering stimulation technologies such as casing-while-drilling (CWD) in mature oilfields and stratum-network reengineering; three-dimensional shale oil and gas development technologies integrating "3D well patterns, hydraulic fracture network, and natural fracture network"; maximum reservoir contact (MRC) collaborative development technologies, such as MRC multi-component thermal composite methods for shallow, thin, ultra-heavy oil reservoirs and MRC multi-lateral well configurations for tight gas reservoirs of the West Lake Project in East China Sea. Additionally, we should focus on multi-resource collaborative development technologies, including the synergy between underground gas storage and EOR for reservoirs in oil and gas fields, the co-development of oil/gas fields and geothermal fields, and the co-extraction of multiple mineral resources.
