为提高水基钻井液的润滑性，缓解日益突出的长水平段高摩阻问题，促进水平井钻井技术的持续发展，国 内外开展了大量关于环保高性能水基钻井液润滑剂的研究。介绍了近年来国内外醇醚类、烷基糖苷类、改性植 物油类、复配型、惰性固体类、囊包型润滑剂和极压润滑剂的最新研究进展，并评述了各自的优缺点，在此基础上 对水基钻井液润滑剂的发展进行了展望。

In order to improve the lubrication of water-based drilling fluid，solve the high friction of long horizontal section of horizontal wells and promote the sustainable development of drilling technology for horizontal well，a great number of researches about eco-friendly lubricant with high performance had been conducted at home and abroad. In this paper，the domestic and international research progress of lubricant for water-based drilling fluid was reviewed including alcohol ether，alkyl glycoside， modified vegetable oil，compound lubricant，inert solid，encapsulated lubricant and extreme-pressure lubricant. The advantages and disadvantages of these lubricants were compared. Finally，the development directions of lubricant for water-based drilling fluid were proposed.
