FIELD: oil and gas production.
SUBSTANCE: communication line for bottomhole telemetric systems for control of parameters of drilling consists of cable sections built-in into drilling pipes each including section of cable, contact coupling and rod arranged on different ends of cable and equipped with points of attachment to drill pipes consisting of cases and wedging elements. Also, the cases of the attachment points in their middle part have cross section fit into oval. On external surface in the middle part of the cases along perimetre of section there are made grooves in form of two-edge right angles extended along lengthwise axis of the cases and arranged symmetrically relative to both axes of cross section. The wedging elements are made in form of four identical rectangular plates with their one side installed in the grooves, while with their opposite side resting against internal surface of a drill pipe in its diametrical planes.
EFFECT: raised operational reliability of communication line and versatility of its implementation with pipes of different diameter.
