摘要： A shifting tool (10) for use in a well having a substantially annular completion structure therein, the completion structure having portions of lesser and greater inner diameter and an axially-shiftable element (28) associated with the portion of greater inner diameter. The inner diameter of the axially-shiftable element (28) is greater than a diameter of the completion structure portion of lesser inner diameter. The shifting tool (12) comprises: a first shifting tool portion (34) having a first shifting profile (46) associated therewith, the first shifting tool portion (34) being adapted to pass through the portion of lesser inner diameter; and a second shifting tool portion (38) having a second shifting profile (48) associated therewith. The first shifting profile (46) engages the second shifting tool portion (38) to cause the second shifting tool portion (38) to move with the first shifting tool portion (34); and the second shifting profile engages the axially-shiftable element (28) to cause the axially-shiftable element (28) to move with the second shifting tool portion (38).
摘要翻译：一种用于在其中具有基本上环形的完井结构的井的移动工具（10），所述完井结构具有较小和较大内径的部分以及与较大内径部分相关联的可轴向移动的元件（28）。轴向移动元件（28）的内径大于较小内径的完井结构部分的直径。换档工具（12）包括：具有与之相关联的第一变速轮廓（46）的第一变速工具部分（34），第一变速工具部分（34）适于穿过较小内径的部分; 以及具有与其相关联的第二换档轮廓（48）的第二换档工具部分（38）。第一移动轮廓（46）接合第二换档工具部分（38），以使第二换档工具部分（38）与第一换档工具部分（34）一起移动; 并且所述第二移动轮廓接合所述可轴向移动的元件（28）以使所述可轴向移动的元件（28）随着所述第二移位刀具部分（38）移动。
