CA 2699895

A technique enables anchoring of a tool in a wellbore. The technique utilizes one or more arms pivotably mounted to a structure for movement between a radially inward position and radially outward position that anchors the tool to a surrounding wall. A wedge component is positioned to selectively engage the arms. When relative axial movement is caused between the wedge component and the arms, the arms are pivoted to a desired radial position.

Selon l'invention, une technique permet l'ancrage d'un outil dans un forage de puits. La technique utilise un ou plusieurs bras montés avec une possibilité de pivotement sur une structure en vue d'un mouvement entre une position radialement vers l'intérieur et une position radialement vers l'extérieur qui vient ancrer l'outil sur une paroi qui l'entoure. Un composant de calage est positionné pour se mettre sélectivement en prise avec les bras. Lorsque le mouvement axial relatif est provoqué entre le composant de calage et les bras, on fait pivoter les bras vers une position radiale souhaitée.
