Patent

CA 2501599

A method and apparatus are provided for installing control lines and pipe into a well. The pipe-holding spider that is normally mounted on the rig floor is supportably retained in a vertically movable retainer. The retainer is adapted for controllably elevating the spider above the rig floor when the pipe slips within the spider are not engaged with the outer surface of the pipe string, thereby providing personnel access to a portion of the length of the pipe string below the elevated spider and above the rig floor. Personnel are provided with access to the pipe string for applying a fastener to secure the control line to the pipe string.

L'invention concerne un procédé et un appareil (10) permettant d'installer des lignes de télécommande et un tuyau (14) dans un puits. L'araignée de support du tuyau, qui est normalement montée sur le plancher de l'installation de forage, est retenue à l'aide d'un support dans un dispositif de retenue verticalement amovible. Le dispositif de retenue est adapté pour élever de manière contrôlée l'araignée (11) au-dessus du plancher de l'installation de forage lorsque les coins (24) de retenue du tuyau dans l'araignée ne viennent pas en contact avec la surface extérieure du train (14) de tiges, permettant ainsi au personnel d'avoir accès à une partie de la longueur du train de tiges en dessous de l'araignée élevée et au-dessus du plancher de l'installation de forage. Le personnel a accès au train de tiges pour appliquer un dispositif (34) de serrage permettant de fixer la ligne de télécommande au train de tiges.
