Abstract

Il est décrit un localisateur dont la configuration lui permet de se coupler à un train de forage afin de trouver un élément dun puits de forage. Le localisateur comprend un élément extensible, une chambre, un conduit dalimentation en fluide hydraulique ainsi quune source de fluide hydraulique. Capable de se déplacer par rapport au train de forage, lélément extensible adopte par défaut la position allongée par rapport à celui-ci. À la position complètement allongée, lélément extensible peut engager lélément du train de forage. Disposée de manière à entrer en communication fluidique sous pression avec lélément extensible, la première chambre comprend un volume dont la configuration lui permet de changer en fonction dun changement de la position de lélément extensible, et ce, de sorte que lexpansion de la première chambre corresponde à un allongement de lélément extensible et que le rapetissement de la première chambre corresponde à une rétraction de lélément extensible. La source de fluide hydraulique est en communication fluidique avec la première chambre par lintermédiaire du conduit dalimentation en fluide hydraulique. La configuration de la source de fluide hydraulique lui permet de fournir du fluide hydraulique à la première chambre par suite dune expansion du volume de cette dernière entraînée par lallongement de lélément extensible.
