Abstract

A system for coupling a pipe segment to a pipe string is provided that includes a top drive assembly having a threaded output shaft; and a pipe running tool threadingly coupled to the threaded output shaft of the top drive assembly such that the primary load of the pipe running tool is supported by the threads of the output shaft of the top drive assembly, and wherein the pipe running tool is rotatable by the output shaft and further includes a pipe engaging portion for grippingly engaging the pipe segment sufficient to transmit a torque from the top drive output shaft to the pipe segment.

Claims (13)

1. ~A system for coupling a pipe segment to a pipe string comprising:
a top drive assembly having a threaded output shaft; and a pipe running tool threadingly coupled to the threaded output shaft of the top drive assembly such that the primary load of the pipe running tool is supported by the threads of the output shaft of the top drive assembly, wherein the pipe running tool is rotatable by the output shaft and further comprises a pipe engaging portion for grippingly engaging the pipe segment sufficient to transmit a torque from the top drive output shaft to the pipe segment.
2. ~The system of claim 1, wherein an upper end of the pipe running tool comprises an extension shaft was is threadingly coupled to the threaded output shaft of the top drive assembly.
3. ~The system of claim 2, wherein a lower end of the pipe running tool comprises a pipe engaging portion, which engages a pipe segment, such that the weight of the pipe string is carried by the extension shaft of the pipe running tool.
4. ~The system of claim 3, wherein the extension shaft is connected to the pipe engaging portion by a shoulder abutting connection.
5. ~The system of claim 3, wherein a lower end of the extension shaft comprises a lift cylinder that abuts a shoulder of a lift cylinder housing, which is threadingly coupled to the pipe engaging portion.
6. ~The system of claim 5, wherein the pipe engaging portion grippingly engages an internal diameter of the pipe segment.
7. ~The system of claim 6, wherein the pipe engaging portion comprises a tapered slip cone section which slidably receives corresponding tapered surfaces of a plurality of slips, such that a vertical force on the slips causes the slips to move radially outwardly into gripping engagement with the internal diameter of the pipe segment.
8. ~The system of claim 7, wherein the vertical force applied to the slips is sufficient to allow the gripping engagement of the slips with the internal diameter of the pipe segment to transmit a torque from the top drive output shaft to the pipe segment.
9. ~The system of claim 8, wherein a slip cylinder applies the vertical force to each of the plurality of slips.
10. ~The system of claim 9, wherein the slip cylinder comprises a head portion, a shaft portion, and a plurality of feet attached to the shaft portion, wherein each foot is attached to a corresponding one of the slips.
11. ~The system of claim 10, wherein the slip cone section comprises a first tapered section and a second tapered section separated by a radially inward step, and wherein each of the plurality of slips comprises a first tapered section and a second tapered section separated by a radially inward step.
12. ~The system of claim 3, wherein the pipe engaging portion grippingly engages an external diameter of the pipe segment.
13. ~The system of claim 12, wherein the pipe engaging portion comprises a housing with a central opening for receiving the pipe segment and a plurality of slips moveable between a disengaged position and an engaged position wherein the slips grippingly engage the external diameter of the pipe segment.
