Electrical wiring for drill pipe, casing, and tubing

摘要

Disclosed is an apparatus for joining electrical wiring in sections of at least one of a drill pipe, casing and tubing when used to locate and produce hydrocarbons in underground environments. The disclosure notes that industry standards with respect to pipe section diameters can make it difficult to incorporate wiring into pipe sections. The apparatus comprises a first pin (1100) and a second pin. The first pin (1100) has a first joint section. The first joint section has first holes extending a length of the first joint section and the holes terminate at a first preload face. The second pin has a second joint section. The second joint section has second holes extending a length of the second joint section and the second holes terminate at a second preload face. The second joint section receives the first joint section wherein the first holes match the second holes when the first and second pins are mated. The apparatus further comprises first (1104) and second tapered splines. The first tapered splines (1104) on the first pin (1100) extend outwardly from an exterior surface of the first pin (1100) and axially from the first preload face. A spline (1104) of the first tapered splines (1104) has a base at the first preload face and a width that narrows towards a tip of the spline (1104). The second tapered splines on the second pin extend outwardly from an exterior surface of the second pin and axially from the second preload face. A spline of the second tapered splines has a base at the first preload face and a width that narrows towards a tip of the spline. The first tapered splines (1104) are adapted to be received by second tapered splines when the first pin and second pin are mated.
