Definitions

  • the interior side wall is not sufficiently smooth or round to create an effective sealing surface.
  • the internal gripping elements are designed to lock when the drive connection is rotated in a right hand sense, and no means are provided for selectively releasing the internal gripping elements while the drive connection is being rotated in a right hand sense. For these reasons, the sealing potential of the threaded upper end of the casing (which is machined to act as an excellent sealing surface) is not used and the associated advantages are lost.
  • the present invention is directed to an improved apparatus for applying torque to a drilling tubular such as a large diameter casing, which overcomes the disadvantages described above.
  • FIGURE 7 is an elevational view in partial cutaway of a second preferred embodiment.
  • FIGURE 8 is a cross section taken along line 8-8 of FIG. 7.
  • FIGURE 14 is a perspective view of one of the jaws of the embodiment of FIGS. 7-13.
  • a total of six jaws 60 and two shafts 62 are provided.
  • Two diametrically opposed jaws 60 are mounted to the lower ends of the shafts 68 so as to rotate with the shafts 68.
  • the remaining jaws 60 rotate about the pins 66 which are threadedly engaged with the lower end 46 of the body 42.
  • the upper ends of the shafts 68 are provided with splines 88 shaped to engaged correspondingly shaped openings in torque arms 90.
  • These torque arms 90 extend laterally away from the body 40 along a plane transverse to the axis of the passageway 48, and each of the torque arms 90 defines a slot 92 at its outer end.
  • a drag ring 93 is positioned to encircle the body 40, as best shown in FIG. 5. This drag ring 93 is supported in place by fasteners 94 positioned to slide in the slots 92.
  • a friction brake 96 is mounted to the top head drive assembly 14. This friction brake 96 includes brake shoes 98 positioned to engage the drag ring 93 frictionally.
  • the lower end of the passageway 208 terminates in a mud nozzle 212, and the lowermost end of the mud nozzle 212 terminates in a basket made up of a flange 214 and a circumferential rim 216.
  • the rim 216 defines an array of openings 218.
  • first outer ends 230 engage an interior surface 30 of the casing 26 for clockwise rotation of the casing 26 (as seen from above), and the second outer ends 232 engage the interior surface 30 in order to rotate the casing 26 in a counter-clockwise direction.
