摘要 |
A downhole tool for a dual member drill string for detecting information and sending a signal containing that information up a wireline. The tool comprises a beacon supported on a housing for collection of orientation information. The wireline is located within a drill stem in the housing. The beacon communicates a signal to the wireline using a slip ring or a receiver for receiving a wireless signal from the beacon. The downhole tool may have a steering feature such as a deflection shoe for changing the path of the downhole tool.
