Abstract
An improved pipe section for use in a telemetering drill string in which each pipe section contains an insulated electrical conductor extending between insulated electrical connectors in the pipe joints. The improvement comprises encasing the conductor and insulating material in a fluid-tight metal conduit to isolate them from the fluid in or around the drill string when the pipe sections are interconnected.
