Title (EN) DRILL PIPE TORQUE REDUCER AND METHOD
(FR) APPAREIL ET PROCÉDÉ DE RÉDUCTION DE COUPLE DE TRAIN DE TIGES DE FORAGE
Abstract:
(EN) An apparatus and method for reducing torque in a drill string, in winch the apparatus includes a first clamp assembly including a plurality of arcuate clamp segments that are pivotallv connected together, the plurality of arcuate clamp segments being configured to be positioned around and secured to an oilfield tubular so as to be rotationally fixed to the oilfield tubular, and an outer sleeve positioned around the first clamp assembly. The outer sleeve includes at least two sleeve segments assembled together to form a generally cylindrical sleeve around the first clamp assembly, and the first clamp assembly is configured to rotate with the oilfield tubular and with respect to the outer sleeve.
(FR) La présente invention concerne un appareil et un procédé de réduction de couple dans un train de tiges de forage, l'appareil comprenant un premier ensemble de serrage qui comprend une pluralité de segments de serrage arqués qui sont raccordés ensemble de manière pivotante, la pluralité de segments de serrage arqués étant configurés pour être positionnés autour d'un élément tubulaire de champ pétrolifère, et fixés à ce dernier, de façon à être fixés en rotation à l'élément tubulaire de champ pétrolifère, et un manchon extérieur positionné autour du premier ensemble de serrage. Le manchon extérieur comprend au moins deux segments de manchon assemblés ensemble pour former un manchon généralement cylindrique autour du premier ensemble de serrage, et le premier ensemble de serrage est conçu pour entrer en rotation avec l'élément tubulaire de champ pétrolifère et par rapport au manchon extérieur.
