| 摘要 | A system, method and apparatus for using a tool in a borehole is disclosed. The tool is disposed in the borehole. The tool includes a member rotatable substantially independently of the tool. The member is slidably coupled to a wall of the borehole. The tool is conveyed through the borehole to produce a rotation of the member as a result of the slidable coupling between the member and the wall of the borehole. A parameter of axial motion is determined from an angle of rotation of the member. | ||

| 主权项 | 1. A method of using a tool in a borehole, comprising: disposing the tool in the borehole, the tool including a member rotatable independently of the tool; coupling the member to a wall of the borehole; conveying the tool through the borehole to produce a rotation of the member as a result of the coupling between the member and the wall of the borehole; determining a parameter of axial motion of the tool through the borehole from an angle of rotation of the member; and using the tool based on the determined parameter of axial motion. | ||
