A hydraulic tool assembly for a downhole tool comprises a body (12), first and second members (14, 16) mounted for independent movement with respect to the body, and first and second control fluid chambers (24, 26) associated with the respective first and second members. Movement of the first member (14) between a first position and a second position in response to an applied force displaces control fluid from the first chamber (24) into the second chamber (26), to move the second member from a first position towards a second position to execute a tool function.
La présente invention concerne un ensemble outil hydraulique destiné à un outil de fond de puits, comprenant un corps (12), des premier et second éléments (14, 16) montés pour effectuer des mouvements indépendants par rapport au corps, et des premier et second compartiments de liquide de commande (24, 26) associés aux premier et second éléments respectifs. Le mouvement du premier élément (14) entre une première position et une seconde position en réponse à l'application d'une force, provoque le déplacement d'un liquide de commande du premier compartiment (24) vers l'intérieur du second compartiment (26), afin de faire se déplacer le second élément d'une première position à une seconde position pour mettre en oeuvre une fonction d'outil.
