摘要: 南海西部陵水区块平均水深1 710.00 m，区域海况恶劣，为了提高导管下入作业效率，保证水下井口的稳定性，采用喷射钻井技术下导管。对陵水区块海底浅层土壤进行取样分析，得到了导管承载力曲线；对导管载荷进行分析，确定了区域导管安全入泥深度；在综合分析喷射钻井技术与钻具组合特点的基础上，对钻头伸出量、钻头直径、钻压和水力参数进行了优选，确定了导管入泥深度。陵水区块5口井应用了喷射下导管技术，结果表明，井口稳定性均较好，导管下入过程顺利，没有出现导管下沉或倾斜的问题。陵水区块超深水井喷射下导管技术的成功应用，为以后类似超深水井的钻井作业提供了技术参考。Abstract: The sea area of Lingshui Block in Western South China Sea is rough with average water depth of 1710.00 m. In this paper, jet drilling technology was used to run in conductors in order to ensure the stability of underwater wellheads and improve running efficiency of conductors. First, the load capacity curve of conductors was plotted by analyzing the soil samples taken from shallow sea beds in Lingshui Block. Second, the safe driving depth of conductors in this block was determined by analyzing the load on conductors. Finally, bit stick-out, bit diameter, WOB and hydraulic parameters were optimized by analyzing comprehensively the characteristics of jet drilling technologies and BHA (bottom hole assembly) used for ultra-deep water environments, and then the driving depth of conductors was determined. The jetting-based conductor running technology was applied on 5 wells in the Lingshui Block. Results showed that wellheads in this block were of good stability. The conductors were then run in holes successfully without deviation or subsidence. The successful application of jetting-based conductor running technology of Lingshui ultra-deep water block provides the technical inference for the drilling of similar ultra-deep water wells in the future.
