CA 2636707

A method and apparatus are provided for installing control lines and pipe into a well. The pipe-holding spider (12) that is normally mounted on the rig floor is adapted f easy disassembly and reassembly when the pipe slips (60, 62) within the spider are not engaged with the outer surface of the pipe string so that upon disassembly, a control line guide (80) becomes vertically movable. The control line guide is adapted for being controllably elevated to a distance above the rig floor, thereby providing personnel access to a portion of the length of the pipe string below the elevated control line guide and above the rig floor for securing control line to the pipe string using a fastener.

La présente invention concerne un procédé et un appareil permettant l'installation de lignes de commande et de tube dans un puits. Le collier à coins de support de tube qui est normalement monté sur le plancher du ponton d'exploitation est adapté pour être facilement démonté et monté lorsque les coins de retenue de tube à l'intérieur du collier à coins ne sont pas engagés avec la surface extérieure de la colonne de tubes de sorte que lors du démontage, un guide de ligne de commande devienne verticalement mobile. Le guide de ligne de commande est adapté pour être soulevé de manière contrôlée à une distance au-dessus du plancher du ponton d'exploitation, assurant ainsi l'accès du personnel à une partie de la longueur de la colonne de tubes en-dessous du guide de ligne de commande soulevé et au-dessus du plancher de ponton d'exploitation pour solidariser la ligne de commande à la colonne de tubes à l'aide d'une attache.
