综述了国外近期深井钻井实践，探讨了深井钻井中深井钻井模拟技术、优化设计技术、近平衡钻井技术、钻头选型技术，应用井下动力钻具提高钻速技术，使用顶部驱动系统和随钻测量系统技术，深井钻井液技术和建立钻井分析及指挥中心等可行性技术，同时指出了我国深井钻井技术应开展的主要工作。 In this paper, the recent practice of deep well drilling in foreign countries is reviewed. The deep well drilling simulation technology, optimization design technology, near equilibrium drilling technology, bit selection technology in deep well drilling are discussed. The technology of downhole drilling is used to improve the drilling penetration rate. The top drive system and measurement while drilling System technology, deep well drilling fluid technology and the establishment of drilling analysis and command center and other feasibility technologies, and also pointed out that China’s deep well drilling technology should be the main work to be carried out.
