Title (EN) WELL TOOL ANCHOR AND ASSOCIATED METHODS
(FR) ÉLÉMENT D'ANCRAGE D'OUTIL DE PUITS ET PROCÉDÉS ASSOCIÉS
Abstract:
(EN) An anchor for securing a well tool can include a longitudinally extending central axis, an outwardly extendable grip member, and a mechanical linkage including multiple pivotably connected links. The links pivot relative to each other in a plane laterally offset from the central axis. A method of anchoring a well tool can include flowing a fluid through an anchor connected to the well tool, thereby outwardly extending a grip member into contact with a well surface, and applying a tensile force to the anchor, thereby increasingly biasing the grip member against the well surface and securing the well tool relative to the well surface. A method of anchoring a tubing cutter in a tubular string can include applying a tensile force from an anchor to the tubular string, and cutting the tubular string while the tensile force is applied from the anchor to the tubular string.
(FR) Élément d'ancrage pour fixer un outil de puits pouvant comprendre un axe central s'étendant longitudinalement, un élément de préhension extensible vers l'extérieur, et une liaison mécanique comprenant de multiples liaisons reliées de manière pivotante. Les liaisons pivotent les unes par rapport aux autres dans un plan décalé latéralement par rapport à l'axe central. Un procédé d'ancrage d'un outil de puits peut consister à faire s'écouler un fluide à travers un élément d'ancrage relié à l'outil de puits, ce qui permet d'étendre vers l'extérieur un élément de préhension en contact avec une surface de puits, et à appliquer une force de traction à l'élément d'ancrage, ce qui permet de solliciter de plus en plus l'élément de préhension contre la surface de puits et d'immobiliser l'outil de puits par rapport à la surface de puits. Un procédé d'ancrage d'un dispositif de découpe de colonne de production dans un train de tiges tubulaires peut consister à appliquer une force de traction d'un élément d'ancrage au train de tiges tubulaire, et à découper le train de tiges tubulaires tandis que la force de traction est appliquée de l'élément d'ancrage au train de tiges tubulaires.
