摘　　要：钻井周期学习曲线可以用来评价作业者/承包商的作业技术能力、管理水平和学习能力。通过钻井周期学习曲线的参数敏感性分析,提出影响建井工期的显著因素是最优钻井周期,考虑到实际操作性,加强经验积累、优化管理程序、提高学习能力是缩短钻井周期的最经济有效的措施。结合几种不同形式的钻井周期曲线,分析出具体作业过程中可能出现的问题。通过对南海某区块深水钻井钻井周期的分析,对该钻井平台及作业者的作业能力进行了简要的评价。提出的方法和结论可为作业者合理制定工期计划、评价承包商作业能力提供参考。Drilling period learning curve can be used to evaluate the operating capability, management level and learning ability of operator and contractor. In this paper, sensitivity analysis is done to present that the optimum drilling period is the prominent factor affecting the drilling period, but in fact, the more available way to decrease drilling period lies on more experience, optimized management procedure and improved learning ability. According to different kind of drilling period learning curve, the related abnormal operating conditions are illustrated. The drilling period learning curve is found according the practical period of one operator. The method and conclusion can be referenced by operator to design a reasonable drilling project time and rank the contractor＇s operating capability.
