易钻桥塞-连续油管磨铣管串 Milling Tool String
Thru-Tubing Milling
Plugs can be milled post-frac underbalanced using coiled tubing or snubbing unit. 压裂作业完成后的桥塞 可以用连续油管和不压井作业井来进行 磨铣作业 Special high-torque motor and specialist high performance mill offered to mill out plugs 采用高扭矩马 达和高扭矩磨鞋进行磨铣作业 Average mill-out time is only 25-30 minutes per plug 平均一个桥塞磨铣所 需时间仅25-30分钟 Up to 20 plug in one trip is possible 单 趟可实现磨掉 高达20个桥塞
速 Can be fished with standard tools 能够使用标准打捞工具进行 打捞回收 Minimal coiled tubing deformation 减小了连续油管的变形量 Rotationally locked with set screws 使用调节螺钉旋转固定 Suitable for all motor and fishing applications适用与所有的马达 作业和打捞作业
计用于抵抗高频率的振动冲击和震击负荷 Internal and external debris barrier内部和外部都有栏砂屏 Short length 长度短 Increased ID allows for high flow rates 增大内径以获得更高的流速 Special torque through spear available 整个打捞矛会有一个特殊的扭矩 Flow through capability after disconnecting 断开后流体断开

双驱动循环阀Dual Actuated Circulation Valve
Ball Actuated
投球启动 Enables circulation without motor operating 不用马达也可实现循环 Rupture disc allowing for ability to circulate in event of plugged BHA 如果井下钻具发生堵塞破裂盘可以让循环继续 Large ID allows for high flow rate 大内径高流速
钻塞过程 Milling Process
连续油管下入 磨铣工具
齿合式设计使上面桥塞剩 余部分和下部桥塞锁紧， 防止磨铣时的转动
低密度钻屑很容易随 着循环液返出到井口
桥塞完全磨掉，有效 防止了底层污染，得 到了干净的井筒。

易钻桥塞-连续油管磨铣程序 Milling Procedure
1. 安装连续油管设备组件和井口防喷器等地面设备。 Rig up Anton CTU Equipmented
1.75” Coil Tubing, rig up CTU with 15K BOP and Lubricator. 2. 上提15klb对连续油管接头进行上提测试, 或根据具体作业情况确定提升力的大小 . 然后重新上紧连续油管接头以确保卡瓦完全咬合上连续油管, 并拧紧紧固螺丝. Perform a pull test on the connector to 15,000 lbs, or as per programme, and re-torque the connector to ensure that it is fully bedded in on the grapple. Tighten the set screws. 3. 用所要求的最大尺寸的球对整个连续油管组件通径, 核实每一部件所需球的尺寸. Drift all components with largest ball required to pass through the component, verify ball size of all components. 4. .连接双瓣回压阀, 并根据甲方的要求对回压阀做压力测试, 确保回压阀能正常工 作. Attach the Dual Back Pressure Check Valves and perform pressure tests according to the coiled tubing company’s standards to ensure that the flapper check valves are functioning correctly 5. 打开立管,根据上页提到的管串链接钻具组合 .Open the riser and attach the remaining to complete the BHA as last slide
1、扭矩和转数适中，工具短，适宜钻塞、旋转冲
洗等；适宜的最小管子内径2″ 2、可用流体/空气/泡沫作为驱动 3、高达200℃的工作能力。
