Shifting tool for a subterranean completion structure

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). <IMAGE>
