With the continuous increase in global energy demand, the efficiency of low-permeability oil reservoir exploitation urgently needs to be improved. In recent years, nano-displacement agents, as an emerging technology to enhance oil recovery, have attracted significant attention. This study reviews the research progress of nano-displacement agents in enhancing oil recovery from low-permeability reservoirs and explores their potential applications in low-permeability reservoirs with poor permeability and restricted fluid mobility. The definition and classification of nano-displacement agents clarify their diversity in different application scenarios, while various preparation methods provide possibilities for optimizing their performance. Through an in-depth analysis of the characteristics of low-permeability reservoirs, their unique permeability properties and technical challenges in exploitation are defined, pointing out the limitations that traditional displacement methods cannot overcome. By assessing multiple domestic and international case studies, it is proven that nano-displacement agents can enhance displacement efficiency in practical applications and show promising economic prospects. However, at the technical level, challenges still exist in terms of preparation costs, environmental impact, and large-scale application. This paper proposes future research directions, including technological innovation, market application prospects, and the potential for interdisciplinary cooperation, aiming to provide theoretical basis and reference for the further development of nano-displacement agents.
