An annular coil wire being laid within the annular MCEI trough; the coil wire being connected to coaxial cable within the tool. The coaxial cable comprising a mesh reinforced polymeric composite dialectic material intermediate a center electrical conductor and an outer electrically conducting sheath. The dialectic material comprising MCEI fibers in sufficient volume to capture an electromagnetic field surrounding the center conductor and shield a signal being transmitted along the center conductor from outside electromagnetic interference. The center conductor may run through MCEI mesh reinforced beads embedded within the dialectic material. The coaxial cable may extend within the tool or to the opposite end of the tool with the center conductor being connected to a similarly configured inductive coupler.

摘要： A resilient electrical conductor for an inductive coupler assembly comprising a loop comprising first and second ends. The first and second ends being harder than the loop. The loop is located within an annular recess in the top wall of a cylindrical housing. A magnetically conductive electrically insulating, MCEI, channel surrounding the loop provides a transmission element for the electromagnetic field produced by the loop when energized. The first end is configured for connection to a transmission line and the second end is configured for attachment to ground. The wire loop comprises one or more helical segments between the first end and the second end, each segment comprising a plurality of turns. The annular recess may comprise a step in the side wall of the cylinder joining the side wall with the top wall. The segments may comprise vertical coils attached in series or in parallel to the loop.

摘要： A cylindrical tool string assembly for downhole data transmission comprises a cylinder comprising a transmission element such as an inductive coupler installed within a groove in its top surface connected to a transmission line housed within its exterior wall. The assembly includes a split spring ring housed within a groove formed in a bore wall of a tool string component such as a drill pipe or a downhole tool within the bottom hole assembly. The spring ring may be compressed and released when positioned within the groove. The spring ring provides a platform on which cylinder may be mounted. The split provides a passageway for the transmission line to exit the cylinder. The cylinder includes a recess in its top surface housing an extractor to facilitate removal of the cylinder. An anti-rotation lock between the cylinder and bore of the tool string component may prevent movement of the cylinder.

摘要： A drill string tool comprising a tube comprising a bore and a bore wall having externally and internally upset end portions in the bore wall. The upset end portions comprising one or more axial grooves in the bore wall open to the bore of the tube. The upset end portions further comprising a conical weld surface comprising an annular shoulder. The one or more axial grooves may be formed in the upset portions subsequent to forming the internal upset. Or, the axial grooves may be formed using a die and an internal upset mandrel comprising one or more axial lobes when the internal upset is formed in the bore wall. The upset end portions of the tube may be attached by friction welding to pin end and box end tool joints. The pin end and box end tools joints may comprise a conical weld surface comprising an annular shoulder.
