Title (EN) DOWNHOLE VIBRATION ASSEMBLY AND METHOD OF USING SAME
(FR) ENSEMBLE VIBRATOIRE DE FOND DE TROU ET PROCÉDÉ D'UTILISATION
Abstract:
(EN) A vibration assembly of a drilling tool for drilling a wellbore penetrating a subterranean formation is disclosed. The downhole drilling tool includes a drill string, a bottomhole assembly and a drill bit. The vibration assembly includes a housing (334a) operatively connectable to the bottomhole assembly, expanders (122) positionable in the housing and radially extendable and retractable thereabout, and a radial vibrator (comprising mandrel (446), enlarger spring (48), cam portion (458) and vibration spring (570) operatively connectable to the expanders to vibrationally move the expanders against the wall of the wellbore whereby movement of the downhole tool is altered during drilling.
(FR) L'invention concerne un ensemble vibratoire d'un outil de forage pour forer un puits de forage pénétrant dans une formation souterraine. L'outil de forage de fond de trou comprend un train de tiges, un ensemble de fond de trou et un trépan de forage. L'ensemble vibratoire comprend un logement (334a) pouvant être relié fonctionnellement à l'ensemble de fond de trou, des extenseurs (122) pouvant être positionnés dans le logement et extensibles et rétractables radialement autour de celui, et un vibreur radial comprenant un mandrin (446), un ressort agrandisseur (48), une partie de came (458) et ressort vibrant (570) pouvant être relié fonctionnellement aux extenseurs pour déplacer de manière vibratoire les extenseurs contre la paroi du puits de forage, moyennant quoi un mouvement de l'outil de fond de trou est modifié lors du forage.
