Title (EN) FRICTION BASED THREAD LOCK FOR HIGH TORQUE CARRYING CONNECTIONS
(FR) FREIN-FILET À FRICTION POUR RACCORDEMENTS SUPPORTANT UN COUPLE ÉLEVÉ
Abstract: front page image
(EN)Certain aspects and examples of the disclosure herein are directed to a device for allowing downhole drilling tubing to withstand greater torques. Certain examples may allow a tube segment to experience a higher torque without the need for increasing the tube or thread size. Certain examples provide for a roller or sprag configuration positioned with respect to a tube segment that allows the tube segment to withstand higher torques.
(FR)Certains aspects et exemples de la présente invention portent sur un dispositif pour permettre à un tubage de forage de fond de trou de résister à de plus grands couples. Certains exemples peuvent permettre à un segment de tube de subir un couple plus élevé sans qu'il soit nécessaire d'augmenter la taille de tube de filetage. Certains exemples concernent une configuration de rouleau ou de galet positionnée par rapport à un segment de tube qui permet au segment de tube de résister à des couples plus élevés.
