文中对纳米技术在提高原油采收率方面的应用作了介绍和评述，涉及原理、制备、性能、工艺、现场应用效果等方面。其中，较详细地介绍了改进的纳米粒分散体系和纳米乳液的作用机理及提高采收率的效果，适合复杂地层和苛刻环境的纳米硅凝胶、纳米聚合物微球封堵技术，以及纳米复合压裂增产技术等方面的基础理论研究和应用情况。

The application of nanotechnology in enhancing oil recovery was reviewed in this paper, especially for the mechanism, preparation, property and field application. The mechanism of modified nano-particle dispersion and nano-emulsion and the enhancing oil recovery effect were introduced in detail. The nano-silicate and nano-polymer in water control were applied in the complex formation and harsh environment. The nano-particle in stimulation application was also studied.
