本文综述了近年来纳米材料在钻井流体、完井流体及油气层保护领域的应用研究进展，介绍了纳米复合降滤失剂、复合增黏剂、润滑剂、水泥浆、隔离液和储层保护材料等纳米材料，它们在稳定井壁、改善固井质量及保护储层等方面都能起到极其重要的作用。最后，对纳米材料在钻井完井流体和油气层保护领域的应用前景进行了相应的展望。

In this paper, the applications of nanomaterial in the fields of drilling fluids, completion fluids as well as reservoir protection in recent years were reviewed. The nanomaterials used as nanocomposite filtration-reducing agent, nanocomposite viscosifier, nanosized lubricant, nano-cement slurry, nano-spacer, nanomaterials for reservoir protection, and so on, were introduced, which had played an essential role in maintaining borehole stability, improving cementing quality and protecting reservoir. Finally, the further application of nanomaterial in drilling/completion fluids and reservoir protection is also prospected.
