Title (EN) ROTOR BEARING FOR PROGRESSING CAVITY DOWNHOLE DRILLING MOTOR
(FR) PALIER DE ROTOR POUR MOTEUR DE FORAGE DE FOND DE TROU À VIS EXCENTRÉE
Abstract:
(EN) A progressing cavity drilling motor positionable in a wellbore includes a tubular housing, a stator having a collection of helical lobes, and a rotor having a collection of helical lobes. The rotor orbits about the central longitudinal axis of the stator. A bearing assembly is coupled to an end of the housing and is disposed around an end of the rotor. The bearing assembly includes a bearing housing disposed concentrically in the stator housing, an outer bearing disposed concentrically in the bearing housing, and an inner bearing disposed on the first cylindrical end of the rotor. The inner bearing has a central axis aligned with the central axis of the rotor and is positioned in the outer bearing such that the inner bearing orbits around the central longitudinal axis of the stator when the rotor is rotated in the stator.
(FR) La présente invention concerne un moteur de forage à vis excentrée pouvant être positionné dans un puits de forage, comprenant un logement tubulaire, un stator ayant un ensemble de lobes hélicoïdaux, et un rotor ayant un ensemble de lobes hélicoïdaux. Le rotor tourne autour de l'axe longitudinal central du stator. Un ensemble palier est accouplé à une extrémité du logement et est disposé autour d'une extrémité du rotor. L'ensemble palier comprend un logement de palier disposé de manière concentrique dans le logement de stator, un palier extérieur disposé de manière concentrique dans le logement de palier, et un palier intérieur disposé sur la première extrémité cylindrique du rotor. Le palier intérieur possède un axe central aligné avec l'axe central du rotor et est positionné dans le palier extérieur de sorte que le palier intérieur tourne autour de l'axe longitudinal central du stator lorsque le rotor est entraîné en rotation dans le stator.
