TOP FEED OF CONTROL LINES TO A RECIPROCATING SPIDER
Abstract:
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.
