apparatus and method for controlling a well device in an oil, gas or water well

摘要

apparatus and method for controlling a well device in an oil, gas or water well is described herein by an apparatus for controlling a well device in a well, comprising a body having a control slot that utilizes a peg. movement of the pin relative to the control slot switches the device between active and inactive states. the slot has at least one bend and at least one elongate axial track distributed around the body relative to at least one bend. the pin may move in at least one elongate axial track between the different pin and slot configurations corresponding to the active and inactive well device configurations. each of the at least one elongate axial track is connected to one of the at least one bend through a bypass extension track, and the control slot does not have a separate dedicated return path to return the bypass extension pin to the elongated axial trail. 1/1
