Method and apparatus for installing control lines in a well

Abstract

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.

1 . An apparatus for installing a control line and a pipe string in a well comprising a retainer for reciprocating a spider.  
   
   
       2 . The apparatus of  claim 1  further comprising a plurality of members for supporting the retainer in a raised position above a rig floor.  
   
   
       3 . The apparatus of  claim 2  further comprising a means of raising the spider to its raised position.  
   
   
       4 . The apparatus of  claim 2  wherein a gap is created for providing access to at least a portion of the pipe string beneath the spider in its raised position and above the rig floor for securing the control line to the pipe string.  
   
   
       5 . An apparatus for installing a control line and pipe string in a well comprising a jack for controllably elevating a spider to a raised position above a rig floor.  
   
   
       6 . The apparatus of  claim 5  further comprising a plurality of members for supporting the spider above the rig floor.  
   
   
       7 . The apparatus of  claim 5  further wherein the spider engages the pipe string by radially inwardly movement of a plurality of pipe slips.  
   
   
       8 . The apparatus of  claim 7  wherein the spider is not engaged with the pipe string when the spider is supported by the jack in the raised position.  
   
   
       9 . A method of installing control line and pipe in a well comprising controllably raising a spider to a raised position above a rig floor.  
   
   
       10 . The method of  claim 9  further comprising supporting a pipe string with an elevator, wherein the spider is supportable in its raised position only when the pipe string is supported by the elevator.  
   
   
       11 . The method of  claim 9  further comprising raising the spider to the raised position only when the spider is disengaged from the pipe string.  
   
   
       12 . The method of  claim 10 , further comprising lowering the spider to the rig floor.  
   
   
       13 . The method of  claim 12  further comprising reengaging the spider with the pipe string.
