Oil and gas well drill pipe electrical and communication assembly

Abstract

An electrical transmission assembly for drill pipe segments for a drill string for oil wells and gas wells. A resilient pipe segment lining having an embedded lining conductive element extending from a first lining inductive element to a second lining inductive element is affixed to the interior surface of the pipe segment. A support sleeve dimensioned for slidable mating with the interior surface of the resilient pipe segment lining has an embedded sleeve conductive element extending from a first sleeve inductive element to a second sleeve inductive element. The position of the first and second sleeve inductive elements respectively provide for them to be positioned radially and longitudinally proximal to the first and second lining inductive elements respectively as the pipe segments are threaded together.
