Zusammenfassung: | 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 adapted for easy disassembly and reassembly when the pipe slips within the spider are not engaged with the outer surface of the pipe string so that upon disassembly, a control line guide 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 guide and above the rig floor for securing control line to the pipe string using a fastener. Also disclosed is an apparatus and a method for securing a control line (92) to a tubular string (30) being run into a well (10). The apparatus may comprise a spider (12) having a tapered bowl (20) for receiving slips for engaging and supporting the tubular string. The apparatus may further comprise a control line guide (80) adapted for reciprocation into a slot (25) in the tapered bowl. |
