摘　　要：顺北油气田为受断裂控制的特深碳酸盐岩断溶体油藏,是中石化在塔里木盆地新地区、新领域、新类型获得的重大油气突破。文章归纳总结中石化系统内部关于新井钻井周期预测方法特点,按照定额周期法预测钻井周期运行中存在的问题,分析并确定影响钻井周期变化的主要因素,提出解决油田开发初期定额周期与实际周期差异的方法,确保钻时定额的长期适用性。Shunbei Oil and gas field is an extremely deep carbonate fault solution reservoir controlled by faults,which is a major breakthrough achieved by Sinopec in a new area,new field and new type of Tarim Basin.Therefore,this paper summarizes the characteristics of Sinopec system's internal drilling cycle prediction methods for new Wells,analyzes and determines the main factors affecting the change of drlling cycle in view of the problems existing in the operation of predicting drilling cycle with quota cycle method,and proposes a method to solve the difference between the initial period of oilfield development and the actual period,so as to ensure the long-term applicability of quota during drilling.
