摘　　要：随着全球能源需求的持续增长,低渗油藏的开采效率亟需提升。近年来,纳米驱油剂作为一种新兴的提高采收率技术备受关注。本研究综述了纳米驱油剂在低渗油藏中的提高采收率研究进展,探讨了其对渗透性差、流动性受限的低渗油藏的应用潜力。纳米驱油剂的定义与分类明确了其在不同应用场景下的多样性,而不同的制备方法为其性能优化提供了可能。在对低渗油藏特点的深入分析中,界定了其独特的渗透特性及开采面临的技术难点,指出传统驱油方式难以克服的限制性因素。通过多个国内外案例的评估,证明了纳米驱油剂在实际应用中能够提升驱油效率,并在经济性方面显示出良好的前景。然而,技术层面仍面临制备成本、环境影响及规模应用等挑战。本论文提出了未来的研究方向,包括技术创新、市场应用前景及跨学科合作的可能性,旨在为纳米驱油剂的进一步开发提供理论依据和参考方向。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 o
