Abstract

L'invention concerne un procédé de stabilisation d'au moins une partie d'un chapelet d'outils de fond et un appareil associé. Le procédé comprend la stabilisation de la partie du chapelet d'outils de fond alors qu'un appareil et/ou la partie du chapelet d'outils de fond est/sont dans et/ou traverse(nt) une formation souple comprenant des inclusions dures. Le procédé comprend l'alésage des inclusions dures avec une partie d'alésage d'un appareil de fond alors qu'une partie de stabilisation de l'appareil de fond stabilise la partie d'alésage et/ou la partie du chapelet d'outils de fond.
