Abstract

In the middle and late stages of water-flooding development in oil reservoirs, the intensification of heterogeneity and the high-temperature, high-salinity environment impose greater demands on the implementation of chemical flooding, presenting new challenges for its application. For this reason, this paper provides a comprehensive summary of the application status and existing issues of polymer flooding, surfactant flooding, alkali flooding, and polycomplex flooding technologies. Additionally, it analyzes the current development status of organic alkaline ternary combination flooding, alkaline-free binary combination flooding, non-continuous chemical flooding, and nanocombination flooding technologies. The study identifies technical bottlenecks and challenges in the performance of oil displacement systems regarding stability, adaptability, evaluation methods, and reservoir damage. It also offers an outlook on low-damage chemical flooding systems and the intelligent development of combination flooding technologies. This study serves as a reference for the research and application of chemical flooding in the oil industry.
