Title: Repeatable reference for positioning sensors and transducers in drill pipe

Abstract

A drill pipe having a box end having a tapered thread, and an internal shoulder and an external face for engagement with a drill pipe pin end having a tapered mating thread, and an external shoulder and an external face adapted for data acquisition or transmission. The relative dimensions of the box and pin ends are precisely controlled so that when the tool joint is made up, a repeatable reference plane is established for transmitting power and tuning downhole sensors, transducers, and means for sending and receiving data along the drill string. When the power or data acquisition and transmission means are located in the tool joint, the dimensions of the tool joint are further proportioned to compensate for the loss of cross-sectional area in order maintain the joints ability to sustain nominal makeup torque.
