    摘要： A tubular section and a system including the tubular section include a first tubular member including a threaded pin section and a second tubular member, the second tubular member including a threaded box section configured to mate with the threaded pin section. The tubular section also includes a shoulder ring disposed between the first tubular member and the second tubular member, wherein a wall thickness of at least a portion of the shoulder ring is greater than a smallest wall thickness of the threaded pin section of the first tubular member.

    摘要： A threaded connector that includes a pin end having external threads and a box end having internal threads that are complementary to the external threads has a thread profile that defines at least a portion of either or both of the internal threads and the external threads. The thread profile may include a thread root connecting a first flank to a second flank and the thread root may be at least partially defined by a plurality of tangentially interconnected radii. The plurality of radii may include at least a medial radius, a first distal radius on one side of the medial radius, and a second distal radius on the another side of the medial radius. The medial radius may be larger than the first and the second distal radius. Alternatively, the thread profile includes a thread root connecting a first flank to a second flank that is at least partially defined by a plurality of radii, each radius having a different length and each defining a circular arc.

    摘要： An apparatus for communicating a signal to or from a downhole tool includes a drill pipe configured to be rotated to drill a borehole, a tubular under axial tension and secured in the drill pipe, and a retention device secured to the tubular and configured to maintain the tubular under the axial tension. The retention device includes a portion extending from a body of the device in a direction that is non-inward-radial with respect to a longitudinal axis of the drill pipe. The apparatus further includes a transmission line disposed in the tubular and in an opening of the retention device and in communication with the downhole tool.
