摘　　要：超深水钻井作为深水钻井的一部分,具有海水深(超过1500m)、温度低、海床不稳定、海底潜流大、海底浅层地层松软等难点,对超深水钻井构成了严峻的挑战。超深水表层导管的下入,是建立水下井口、确保后续钻井作业正常进行的基础,如何克服这些挑战并确保表层导管顺利下入是超深水钻井必须克服的难题之一。结合LW-A超深水井的设计与施工,阐述了超深水表层导管的尺寸、强度、长度选择,导管下入风险和控制措施,对超深水钻井技术的发展和成熟奠定了基础。Ultra-deepwater drilling has difficulties such as water depth,low temperature,unstable seabed,large undercurrent on the seabed,and soft seabed,which poses severe challenges to ultra-deepwater drilling.The running of ultra-deep water surface pipes is the foundation for establishing underwater wellheads and ensuring the normal progress of subsequent drilling operations.Combining the design and construction of the LW-A ultra-deep water well,this paper expounds the size,strength and length selection of the ultra-deep water surface conductor,the risk of running the conductor and the control measures.
