Title (EN) METHOD AND DEVICE FOR ACTIVATING AND DEACTIVATING A GS-TOOL
(FR) PROCÉDÉ ET DISPOSITIF PERMETTANT D'ACTIVER ET DE DÉSACTIVER UN OUTIL GS
Abstract:
(EN) Method for activating and deactivating a GS-tool (2) wherein the GS-tool (2) in addition to grippers (22), a tool housing (32) and a spindle (22) comprises a main spring (50) which is arranged to be able to pre-tension the grippers (44) towards a deactivated position, as the GS-tool (2) is displaceable in a wellbore (10) in the ground, wherein the method comprises: - to couple the spindle (22) of the GS-tool (2) to an actuator mandrel (12) of an actuator (4); - to arrange an activating sleeve (16) between the tool housing (32) and an actuator housing (14); and - to displace the actuator mandrel (12) and thereby the spindle (22) relative to the tool housing (32) in a direction from the GS-tool (2) until the grippers (44) have reached their activated positions by overcoming the force from the main spring (50). A GS-tool for implementing the method is also described.
(FR) L'invention concerne un procédé permettant d'activer et de désactiver un outil GS (2), l'outil GS (2) comprenant, en plus d'éléments de préhension (44), d'un boîtier d'outil (32) et d'un axe (22), un ressort principal (50) qui est agencé de sorte à pouvoir prétendre les éléments de préhension (44) vers une position désactivée au fur et à mesure que l'outil GS (2) est déplacé dans un puits de forage (10) dans le sol, le procédé consistant à : coupler l'axe (22) de l'outil GS (2) à un mandrin d'actionneur (12) d'un actionneur (4) ; disposer un manchon d'activation (16) entre le boîtier d'outil (32) et un boîtier d'actionneur (14) ; et déplacer le mandrin d'actionneur (12), et, de ce fait, l'axe (22) par rapport au boîtier d'outil (32) dans une direction allant de l'outil GS (2) jusqu'aux éléments de préhension (44) qui ont atteint leurs positions activées en vainquant la force du ressort principal (50). L'invention porte également sur un outil GS permettant de mettre en œuvre le procédé.
