Summary:A well tool includes a first component, a second component having a passage for receiving the first component, and an anchor assembly. The anchor assembly includes at least one anchor positioned on the first component that is received by at least one profile formed on an inner surface defining the passage of the second component. Either or both of the at least one profile and the at least one anchor include a ramp section that has a ramp contour defined by a ramp tangent. The ramp tangent forms an acute angle with a longitudinal axis of the borehole. A related method includes the steps of forming at least one profile in the second component, the at least one profile including a ramped section; disposing at least one anchor in the first component; and lowering the first component relative to the second component until the first anchor and the first profile align the first component and the second component in a predetermined relative alignment. Selon l'invention, un outil de puits comprend un premier élément, un second élément ayant un passage pour recevoir le premier élément, et un ensemble d'ancrage. L'ensemble d'ancrage comprend au moins un ancrage positionné sur le premier élément qui est reçu par au moins un profil formé sur une surface interne délimitant le passage du second élément. Ledit profil et/ou lesdits ancrages comprennent une section de rampe qui a un contour de rampe délimité par une tangente de rampe. La tangente de rampe forme un angle aigu avec un axe longitudinal du trou de forage. Un procédé associé comprend les étapes consistant à former au moins un profil dans le second élément, ledit profil comprenant une section inclinée ; à disposer au moins un ancrage dans le premier élément ; et à abaisser le premier élément par rapport au second élément jusqu'à ce que le premier ancrage et le premier profil s'alignent au premier élément et au second élément dans un alignement relatif prédéterminé.
