Title
(EN) METHODS AND APPARATUS FOR REMOVING SECTIONS OF A WELLBORE WALL
(FR) PROCÉDÉS ET APPAREILS POUR ÉLIMINER DES SECTIONS D'UNE PAROI DE TROU DE FORAGE
Abstract
(EN)
A downhole tool may include an anchor coupled to a first portion of the downhole tool and configured to engage with a feature of a wellbore to affix the first portion to the feature. The downhole tool may also include a linear actuator coupled to the first portion and to a second portion of the downhole tool, where the linear actuator is configured to move the second portion relative to the first portion and the feature. The downhole tool may further include a cutting head coupled to the second portion and including one or more cutters configured to engage with the feature. The downhole tool may also include a control system configured to obtain remote commands to control the anchor, the linear actuator, the cutting head, or a combination thereof.

Cette invention concerne un outil de fond de trou qui peut comprendre un ancrage accouplé à une première partie de l'outil de fond de trou et configuré pour venir en prise avec un élément d'un puits de forage pour fixer la première partie à l'élément. L'outil de fond de trou peut également comprendre un actionneur linéaire accouplé à la première partie et à une seconde partie de l'outil de fond de trou, l'actionneur linéaire étant configuré pour déplacer la seconde partie par rapport à la première partie et à l'élément. L'outil de fond de trou peut en outre comprendre une tête de coupe accouplée à la seconde partie et comprenant un ou plusieurs éléments de coupe configurés pour venir en prise avec l'élément. L'outil de fond de trou peut également comprendre un système de commande configuré pour obtenir des commandes à distance pour commander l'ancrage, l'actionneur linéaire, la tête de coupe, ou une combinaison de ceux-ci.
