摘　　要：纳米技术是指至少一维尺寸在0．1～100nm范围，并且仅仅由于尺寸的变化而生产极其特殊性能的技术，它包括纳米材料的制备、性能的表征及应用。纳米液是由纳米剂分散于水中的纳米液滴构成的溶液，纳米液在采油领域的应用主要是作为驱油剂，进一步提高原油的采收率。文章主要介绍了纳米液在采油方面的意义、机理及其现状。Nano technology involves materials with one-dimensional size of particle at least in the range of 0.1 to 100 nm and obtaining very special properties just because of the variation of particle size. It includes preparation of nano materials, description of its properties and application. Nano-fluid is a solution that consists of nano liquid droplets formed by nano-composite materials dispersing in water. Nano-fluid is mainly used as an oil displacement agent in oil production to further enhance oil recovery factor. This paper mainly introduces the implication on oil recovery, mechanism and status of nano-fluid.
