Optimal Trajectory Design of Ultra-Deep Horizontal Wells in Halahatang Block

  • 摘要: 哈拉哈塘区块已钻水平井井眼轨道设计虽可以满足施工的需要,但设计的造斜率偏小,定向施工时间较长,导致定向仪器和造斜工具在井底时间长,增加了仪器和工具高温下失效的风险。从造斜率优化的角度出发,分析计算了不同套管可以通过的最大井眼曲率和工具的造斜能力,结合钻井现场造斜工具的实际造斜情况,选择哈拉哈塘区块水平井双增轨道中第一造斜段的造斜率为7°/30m,第二造斜段的造斜率为10°/30m。然后运用Landmark软件计算分析了以下内容:所选造斜率的轨道,垂深变化对造斜率带来的影响是否影响螺杆钻具的选择,造斜率增大情况下管柱能否安全下入井底,摩阻的变化情况。计算结果显示,采用大造斜率设计是可靠的。现场应用表明,优化后的水平井井眼轨道设计更利于控制井眼轨迹,同时缩短了定向施工时间。
    Abstract: Although the original horizontal well trajectory in Halahatang block can meet the demand drilling,its build-up rate is slightly lower,causing long directional time,and extended time of orientation tools in well bottom,which increases the risk of tool failure under high temperature.In order to decrease this hazard,from the view of optimizing build-up rate,the maximum passing curvature of different casing and build-up capacity of tools were calculated.Double-increase trajectory chose a build-up rate of 7 degrees per 30 meters at the first section,and 10 degrees per 30 meters at the second section according to build-up rate on site.Landmark software was used to calculate whether the new trajectory and change in vertical depth affect the choice of PDM,and whether the drilling and casing string can run into the well bottom safely,as well as the change of drag.The calculated results showed that the design with higher build-up rate was reliable. Moreover,field application showed that the optimized profile was favorable for trajectory control and shortened the direction time.
