Inflatable shifting tool

摘要

A shifting tool for moving a movable member attached to a device in a downhole tool includes a body having a bore and a feed port connected to the bore. A diaphragm is mounted on the body for radial expansion to engage the movable member. The diaphragm is coupled to the feed port and is configured to radially expand to engage the movable member when fluid is communicated through the feed port at a predetermined inflate pressure. A position locator is used to locate the downhole device such that the body is positioned to permit the diaphragm to radially expand to engage the movable member.
