Apparatus and method for protecting well bore
A tool is described for running in and/or retrieving a bore protector, the tool comprising first and second assemblies longitudinally slidably connected to each other. Latches are mounted on the first assembly for lateral extension and retraction with respect thereto. The latches are also cooperatively connected to the second assembly for laterally inward movement of the latches upon longitudinal movement of the second assembly relative to the first assembly in a first direction, and for laterally outward movement of the latches upon longitudinal movement of the second assembly relative to the first assembly in a second direction opposite the first direction. Means are provided for selectively moving the second assembly in the first direction, and the latches are yieldably biased laterally outwardly. The invention further includes a bore protector adapted for use with the tool by the provision of the internal latch engagement formations. A method of protecting a bore with the bore protector and tool is also disclosed.
