Liner and Liner Top Issues 尾管和尾管悬挂器问题
• Standard industry estimates indicate a 20 - 25% failure which will require some form of remediation or involve Non-Productive Time 一般估计 20-25% 几率不能成功 ，从而需要补救措施或者导致非生产 耗时。
• Slips – support casing damage, pre-set 卡瓦－套管损伤，提前坐封
• Non-integral packers require multiple trips 非一体的封隔器需要多趟下入
• Must dress liner top 必须磨铣回接筒
• 20-25% failure rate 20-25% 失败率
• Typical liner “squeeze job” will cost about 1 day rig time 典型的 尾管 “挤水泥工作”会耗时一天
• Running a “tie-back” packer will cost about 1 day rig time 下入“Tie-Back”封隔器会耗时一天
传统的尾管悬挂器安装
• Integral packers have a single sealing element 整个封隔器只有一个密封胶筒
• Tortuous fluid flow 曲折的液体流动路径
• Multiple leak paths – depend on cement integrity 多个泄漏途径－取决于固井质量

•Lose circ – squeeze TOL不能建立循环－重 新挤水泥 •Overdispl – squeeze shoe替换过度 – 重新挤 水泥 •Underdispl – drill cement替换不足 – 钻水泥 •Hanger doesn’t function悬挂器没有正常工作 •Setting Tool doesn’t function下入工具没有正 常工作 •Hanger presets悬挂器提前坐封
– Shifts ball seat up将球座向上移位 – Flapper closes关闭阀板 – Flapper assembly shifts down阀板总成向下移位 – Expansion initiated开始膨胀过程
