摘要:
An apparatus for retaining a transmission line within a drill string component is disclosed. In one embodiment, such an apparatus includes a drill string component comprising a bore having an internal diameter. A slot is formed in the internal diameter to receive a transmission line. A first feature within the slot is configured to engage a corresponding second feature on the transmission line and thereby retain an end of the transmission line. A sleeve is inserted into the internal diameter to keep the transmission line within the slot. A corresponding system is also disclosed.

An apparatus for communication with a downhole tool linked to a plurality of wired drill pipes includes a base. In addition, the apparatus includes an extension assembly having a first end pivotally coupled to the base and a second end. Further, the apparatus includes a head assembly pivotally coupled to the second end of the extension assembly. Still further, the apparatus includes an interface connector moveably coupled to the head assembly and configured to connect to an uphole end of the tool string and form an interface link between a surface unit and the downhole tool.

A method for making a conduit for transmitting signals along its length includes forming one or more grooves in at least one of the inner and outer walls of a tubular body that extend substantially to a communicative coupler, and securing one or more conductive wires within the one or more grooves. A conduit for transmitting signals along its length in a borehole environment includes one or more conductive wires extending through and being secured within one or more grooves of a tubular body, the one or more conductive wires in signal communication with a communicative coupler so as to establish one or more wired links. The conduit may include a means for securing the one or more conductive wires within the one or more grooves.

A drill pipe includes a pin end connector, a box end connector, a first communication connector and a second communication connector. The pin end connector includes a first region to form a threaded connection to join sections of the drill pipe together, and the first region includes at least one thread that begins at one end of the first region and ends at the other end of the first region. The box end connector receives the pin end connector, and the box end connector includes a second region to mate with the first region to form the threaded connection. The first communication connector is attached to the pin end connector and is located in the first region; and the second communication connector is attached to the box end connector and located in the second region to form a communication connection with the first communication connector.
