Abstract
L'invention concerne un mécanisme d'ancrage de fond de trou destiné à être utilisé dans des outils de fond de trou. Le mécanisme d'ancrage de fond de trou est généralement constitué d'une pluralité de coulisseaux qui pivotent vers l'extérieur à partir d'un corps d'outil de fond de trou pour venir en prise avec des extrémités distales de celui-ci contre un tubage de puits. Les coulisseaux sont mis en prise de manière fonctionnelle dans des cavités à facettes associées au corps d'outil, ce qui crée des composantes de charge qui agissent dans une direction tangentielle, permettant à un corps d'outil à paroi mince de résister à une force de maintien accrue.
