Method and apparatus for installing control lines (31) and pipe (14) into a well. The pipe-holding spider (11) that is normally mounted on the rig floor is supportably retained in a vertically movable retainer (12). The retainer is adapted for controllably elevating the spider above the rig floor when the pipe slips (24) 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 (34) to secure the control line to the pipe string. The control line is supplied from above the spider and is positioned by a control line guide (16) supported on the spider or retainer to pass through the spider outside the path of pipe gripping members within the spider.
Procédé et appareil permettant d~installer un câble de commande et une colonne de tubes dans un puits. Un croisillon porte-tubes, normalement monté sur le plancher d~une installation de forage, est soutenu par un dispositif de retenue mobile dans la direction verticale. Le dispositif de retenue est conçu pour soulever de façon réglable le croisillon au-dessus du plancher de l~installation de forage lorsque les coins de retenue de la colonne de tubes dans le croisillon ne viennent pas en prise avec la surface extérieure de la colonne de tubes, en permettant ainsi au personnel d~exploitation d~accéder à un tronçon de la colonne de tubes compris entre le croisillon soulevé et le plancher de l~installation de forage, et de fixer le câble de commande à la colonne de tubes au moyen d~une attache. Le câble de commande est amené par le dessus du croisillon et positionné par un guide de câble de commande soutenu par le croisillon ou le dispositif de retenue de manière à passer à travers le croisillon à l~écart des coins de retenue de la colonne de tubes.
