Title (EN) DOWNHOLE TOOL AND METHOD FOR OPERATING SUCH A DOWNHOLE TOOL
(FR) OUTIL DE FOND DE TROU ET PROCÉDÉ D'EXPLOITATION D'UN TEL OUTIL DE FOND DE TROU
Abstract:
(EN) This invention relates to a downhole tool (100) comprising a housing (101), an actuating member (105) which is movable relative to the housing, and at least one tool member (103) which is movable between a retracted position and a radially extended position, wherein the movement of said actuating member (105) induces the movement of said tool member. The tool comprises means (107, 125b) for preventing relative movement of the actuating member (105) and the tool member (103), preferably a profiled cam surface (107) cooperating with a contact surface (125b) of the tool member (103), such that the tool member (103) is locked in the retracted position and in the extended position when the actuating member (105) is in a first position and in a second position respectively.
(FR) La présente invention concerne un outil de fond de trou (100) comprenant un logement (101), un élément d'actionnement (105) qui peut être déplacé par rapport au logement, et au moins un élément outil (103) qui peut être déplacé entre une position rétractée et une position radialement étendue, le mouvement dudit élément d'actionnement (105) entraînant le mouvement dudit élément outil. L'outil comprend des moyens (107, 125b) d'empêcher le mouvement relatif de l'élément d'actionnement (105) et de l'élément outil (103), de préférence une surface de came profilée (107) coopérant avec une surface de contact (125b) de l'élément outil (103), de sorte que l'élément outil (103) est verrouillé dans la position rétractée et dans la position étendue quand l'élément d'actionnement (105) se trouve dans une première position et dans une second position respectivement.
