Definitions

  • This invention relates to an apparatus for handling pipes or tubes during assembly of lengths of tubular pipe to form a string.
  • a tubing string is made up of a number of interconnected pipes or tubes.
  • Each tube is capable of being made up by connecting an externally screw-threaded male end of one tube into an internally screw-threaded female end of another tube.
  • the various interconnected lengths of tube in the form of a string are then fed down a bore hole.
  • the string is raised and lowered from the bore hole using a well-known system of elevators and spiders.
  • elevators and spiders are mounted above a drill rig floor and in order to assemble a string the upper end of a section of pipe is engaged by an elevator and raised sufficiently above a string to allow the new section of pipe to be made up with the upper end of the string by means of a tong.
  • the upper end of the string is held against rotation by a spider incorporating gripping elements known as slips.
  • An object of the present invention is to provide an improved form of spider for dual string systems.
  • a dual string spider comprising first and second body portions each defining a string receiving aperture therethrough and hingedly connected together at one side thereof, and actuator means for separating the two body portions about their hinge by a predetermined amount whereby, in use, the distance between strings passing through the aperture in each body portion can be varied.
  • the actuator means is a piston and cylinder device connected between the first and second body portions.
  • a spider for a dual string system comprising a rigid spider body e.g. of steel which is formed in two cooperating portions 2 and 3 hinged together at 4.
  • Each portion 2 and 3 in its closed position as shown in the drawing defines a pair of slip bowls 5,6 adapted to operatively surround a pair of adjacent parallel strings.
  • Gripping elements or slips are adapted to be located in each slip bowl 5, 6 in known manner.
  • the first portion 2 of the spider has welded thereto an outwardly extending bracket 7 having a vertical pivot pin 8 extending therethrough.
  • a piston 9 Connected to the pivot pin 8 is the outer end of a piston 9 which is associated with an hydraulic cylinder 10 whose other end is pivotably mounted on a vertical pivot pin 11 carried by a bracket 12 which is welded to the second portion 3 of the spider.
  • Each portion 2 and 3 of the spider is mounted on a flat plinth 13 through the intermediary of rollers (not shown) which facilitate movement of each of the two portions of the spider over the surface of the plinth 13.
  • the dual parallel strings operatively associated with the slip bowls 5, 6 during normal operation can be separated from each other by actuation of the piston and cylinder device 9, 10 to cause the centres of the drilling strings to be distanced from each other by a distance sufficient to permit the required tong operation on make up of a pip joint on one string without engagement of the other adjacent string by the nose of the tong.
  • the slip centres can be increased in their spacing to 8.25'' at approximately 100 psi.
  • rollers carried by the underside of each portion 2, 3 of the spider permits the two portions 2, 3 of the spider to be separated from each other about the hinge 4 by movement over the surface of the plinth 13 utilising considerably less power than would otherwise be the case.
