随着油气钻井不断向深部发展，钻遇深部超深部地层温度也越来越高，对钻井技术特别是钻井液技术提出了更高要求。在结合超高温钻井实际需求的基础上，分析了水基钻井液在超高温下的技术壁垒、超高温对水基钻井液效能影响作用，综述了超高温水基钻井液的关键处理剂及其所构建的水基钻井液体系的研究现状，并探讨了超高温水基钻井液的未来发展方向。

With the continuous development of oil/gas drilling to the deep，the temperature of deep and ultra-deep formations drilled are getting higher and higher，which puts forward more requirements for drilling technology，especially technology of drilling fluid. In combination with the actual requirements of ultra-high temperature drilling，the technical barriers of water-based drilling fluid under ultra-high temperature and the effect of ultra-high temperature on water-based drilling fluid performance were analyzed. Research progress of key additives for water-based drilling fluid under ultra-high temperature and water-based drilling fluid system they constructed was described，and the future development direction of water-based drilling fluid under ultra-high temperature was discussed.
