Title
(EN) DOWNHOLE TOOL WITH MULTI-STAGE ANCHORING
(FR) OUTIL DE FOND AVEC ANCRAGE MULTI-ÉTAGES
Abstract
(EN)
A downhole tool includes a tool body and an anchoring device integrated with the tool body. The anchoring device includes a contact pad that is at least partially external to the tool body, the contact pad having multiple stages with different thicknesses. The anchoring tool also includes a first linear actuator and a second linear actuator. The first linear actuator is configured to move the contact pad axially with respect to the tool body to align one of the multiple stages with the second linear actuator. The second linear actuator is configured to apply a radial force to the contact pad.
(FR)
L'invention concerne un outil de fond comprenant un corps d'outil et un dispositif d'ancrage intégré avec le corps d'outil. Le dispositif d'ancrage comprend un patin de contact qui est au moins partiellement extérieur au the corps d'outil, le patin de contact présentant des étages multiples d'épaisseurs différentes. Le dispositif d'ancrage comprend également un premier actionneur linéaire et un deuxième actionneur linéaire. Le premier actionneur linéaire est configuré pour déplacer le patin de contact axialement par rapport au corps d'outil de façon à aligner un des étages multiples avec le deuxième actionneur linéaire. Le deuxième actionneur linéaire est configuré pour appliquer un effort radial au patin de contact.
