摘　　要：纳米技术由于成本效益和环保的方式,在提高石油采收率(EOR)方面引起了极大的关注。用于EOR的纳米颗粒的尺寸通常在1~100 nm的范围内,这可能与各种国际组织略有不同。与相同的细小体积分子相比,纳米颗粒表现出显着不同的性质,由于超小尺寸,其表面的原子浓度高得多。这些颗粒最有用和最引人入胜的特性之一是由于表面积大,特别是在高温下产生巨大的扩散驱动力。以前的研究表明,纳米粒子可以通过将储层润湿性转移到更多的水分润湿和降低界面张力来提高原油采收率,但这一领域仍然在探索中。本文将纳米颗粒分为三类:金属氧化物、有机和无机颗粒。Nanotechnology has attracted a great attention in enhancing oil recovery（EOR） due to the cost-effective and environmental friendly manner. The size of nanoparticles for EOR usually is in the range of 1~100 nm, which may slightly differ from various international organizations＇ standards. Nano-particles exhibit significantly different properties compared to the same fine or bulk molecules because of much higher concentration of atoms at their surface as a result of ultra-small size. In particular, one of the most useful and fascinating properties of these particles is to create a massive diffusion driving force due to the large surface area, especially at high temperature. Previous studies have shown that nanoparticles can enhance oil recovery by shifting reservoir wettability towards more water-wet and reducing interfacial tension, yet this area is still open for discussion. In this paper, nanoparticles were classified into three categories of metal oxide, organic and inorganic particles.
