Abstract

See full text

A borehole drilling communication system that includes a hydraulic drill, a communication module, and a transducer. The hydraulic drill has a drill pipe and a drill head where the communication module is located, The transducer has an input end and is mounted on the drill pipe adjacent the communication module. The communication module includes a first output terminal electrically connected to the drill pipe and a second output terminal electrically connected to the input end of the transducer. The transducer includes a helical conductor that is positioned coaxially over a section of the drill pipe at the drill head, with the helical conductor terminating at an electrically isolated free end. During use in borehole drilling, data sent from the communication module is launched by the transducer and transmitted along the drill pipe as a single conductor transmission line.
