    • A sleeve shifting tool for shifting a slidable sleeve positioned inside of another dowhole tool is described herein. The tool has a housing and a collet apparatus for engaging a slidable sleeve disposed within a downhole tool positioned in a wellbore. The collet apparatus includes at least one collet arm and at least one collet key disposed thereon for engaging the slidable sleeve. The tool also includes a collet activation apparatus for initiating the collet apparatus and force the at least one collet key of the collet apparatus to engage the slidable sleeve. A method of shifting a sleeve positioned in a downhole tool with the sleeve shifting tool described herein is also provided herein.
    • 这里描述了用于移动位于另一个钻孔工具内部的可滑动套筒的套筒移位工具。 该工具具有壳体和夹头装置,用于接合设置在定位在井眼中的井下工具内的可滑动套筒。 夹头装置包括至少一个夹头臂和设置在其上的用于接合可滑动套筒的至少一个夹头键。 该工具还包括用于启动夹头装置并迫使夹头装置的至少一个夹头键接合可滑动套筒的夹头启动装置。 本文还提供了使用本文所述的套筒移位工具来移动定位在井下工具中的套筒的方法。
