Title (EN) ACTUABLE DOWNHOLE TOOLS FOR ATTACHMENT TO TUBULAR STRINGS
(FR) OUTILS DE FOND DE TROU ACTIONNABLES POUR FIXATION À DES RAMES TUBULAIRES
Abstract:
(EN) A downhole tool for receiving a milling tool or other forcing tool includes: a tubular mandrel; an adapter housing coupled to the mandrel; a guide sleeve disposed within the adapter housing; a movable sleeve configured for sliding movement within the guide sleeve; and a retainer positioned uphole of the movable sleeve. The retainer includes an upper annular portion, a lower annular portion, an annular void between the upper and lower annular portions, and a bridge portion extending between the upper and lower annular portions. The upper annular portion is initially fixed to the guide sleeve. The lower annular portion is configured such that downward movement of the lower annular portion causes the movable sleeve to move downward within the guide sleeve. The bridge portion comprises a through- passage and a thin walled segment adjacent the void. Disconnecting the bridge portion permits the lower annular portion to move the moveable sleeve.
(FR) L'invention concerne un outil de fond de trou destiné à recevoir un outil de fraisage ou un autre outil de forçage, comprenant : un mandrin tubulaire; un boîtier d'adaptateur couplé au mandrin; un manchon de guidage disposé à l'intérieur du boîtier d'adaptateur; un manchon mobile conçu pour un mouvement de coulissement à l'intérieur du manchon de guidage; et un élément de retenue positionné en amont du manchon mobile. L'élément de retenue comprend une portion annulaire supérieure, une portion annulaire inférieure, un vide annulaire entre les portions annulaires supérieure et inférieure, et une portion en pont qui s'étend entre les portions annulaires supérieure et inférieure. La portion annulaire supérieure est initialement fixée au manchon de guidage. La portion annulaire inférieure est conçue de telle sorte qu'un mouvement vers le bas de la portion annulaire inférieure amène le manchon mobile à se déplacer vers le bas à l'intérieur du manchon de guidage. La portion en pont comprend un passage traversant et un segment à paroi mince adjacent au vide. La déconnexion de la portion en pont permet à la partie annulaire inférieure de déplacer le manchon mobile.
