Abstract: A method comprising moving a shifting tool in a first direction through a moveable member positioned in a casing of a wellbore, including moving the shifting tool through a shifting tool interface member (STIM) adjacent the moveable member, until the shifting tool is positioned past the moveable member and the STIM. The shifting tool is then moved in a second direction substantially opposite the first direction until the shifting tool and the STIM engage. The shifting tool is then further moved in the second direction, thereby moving the STIM and the moveable member in the second direction, until the STIM substantially simultaneously (1) engages the casing and (2) disengages the shifting tool.

Abstract translation: 一种方法，包括使换档工具沿第一方向移动通过位于井眼的壳体中的可移动构件，包括使移动工具移动通过邻近可移动构件的移动工具接口构件（STIM），直到移位工具位于 可移动成员和STIM。 然后，移动工具沿与第一方向大致相反的第二方向移动，直到移位工具和STIM接合。 然后，移动工具在第二方向上进一步移动，从而沿着第二方向移动STIM和可移动构件，直到STIM基本上同时（1）接合壳体并且（2）使换档工具脱开。
