Abstract
An annular wire harness for use in drill pipe comprising two rings interconnected by one or more insulated conductors. The rings are positioned within annular grooves located within the tool joints and the conductors are fixed within grooves along the bore wall of the pipe. The rings may be recessed within annular grooves in order to permit refacing of the tool joint. The rings are provided with means for coupling a power and data signal from an adjacent pipe to the conductors in such a fashion that the signal may be transmitted along the drill pipe and along an entire drill string.
Claims21
An annular wire harness for use in transmitting power and data in drill pipe, comprising:
- a. ring connected to another ring, or to one or more sensors, by means of one or more insulated conductors;
- b. at least one ring being provided with a means for connecting the conductors to a means for transmitting a power and data signal;
- and
- c. at least one ring being deployed within a length of drill pipe, or down hole tool having an annulus, in such a fashion that a power and data signal may be transmitted through the conductors along the section of the drill pipe which forms at least a portion of a drill string.
