Abstract

Двухупорное резьбовое соединение буровых труб, состоящее из ниппеля и муфты, имеющее наружный и внутренний упорные стыки, в зависимости от его параметров и соотношения сил, необходимых для создания заданных напряжений в опасном сечении ниппеля и во внутреннем упорном стыке, зазор в последнем, при свинченном, но незатянутом соединении, определяется следующей зависимостью:δ=(1-Q/Q)ΔI+ΔI,где Qи Q- силы, необходимые для создания заданных напряжений соответственно во внутреннем упорном стыке и опасном сечении ниппеля;Δlи Δl- удлинение и укорочение резьбового участка соответственно ниппеля и муфты при затяжке соединения.Two-stop threaded connection of drill pipes, consisting of a nipple and a coupling, having external and internal thrust joints, depending on its parameters and the ratio of forces required to create specified stresses in the dangerous section of the nipple and in the internal thrust joint, the gap in the latter, when screwed, but loose connection, is determined by the following relationship: δ = (1-Q / Q) ΔI + ΔI, where Q and Q are the forces necessary to create the specified stresses respectively in the internal thrust joint and the dangerous section of the nipple; Δl and Δl are the elongation and shortening ezbovogo portion respectively and the coupling pin when tightening the connection.
