Embodiments of the present invention relates to hydraulically actuated tools, which may be used to actuate a liner hanger assembly. In one embodiment, the present invention provides a hydraulic setting tool (113) for use in wellbore operations. The setting tool includes a first tubular member (130) and a second tubular member (120) disposed around the outer diameter of the first tubular member. A piston (110) is mechanically attached to an upper portion of the second tubular member and adapted to move axially in relation to the first tubular member. The piston acts to transmit a force to the second tubular member. A slip assembly (162) is operatively connected to the second tubular member and the second tubular member transmits the force to the slip assembly thereby actuating the slip assembly.

Les modes de réalisation de cette invention concernent des outils actionnés hydrauliquement, pouvant être utilisés en vue d'actionner un ensemble de suspension de colonne. Dans l'un de ces modes de réalisation, cette invention concerne un outil de pose hydraulique (113) utilisé dans des opérations de forage. L'outil de pose comprend un premier élément tubulaire (130) et un second élément tubulaire (120) placé autour du diamètre externe du premier. Un piston (110) est relié mécaniquement à une partie supérieure du second élément tubulaire et conçu de manière à se déplacer axialement par rapport au premier. Le piston agit de manière à transmettre une force au second élément tubulaire. Un ensemble coulissant (162) peut être relié fonctionnel au second élément tubulaire, ce dernier transmettant la force à l'ensemble coulissant en vue de l'actionner.
