Q

Connected to the rotary table by four large steel pins that fit into mating holes in the rotary table

A

Kelly Bushing

13
Q

Revolving or spinning section of the drillfloor that provides power to turn the drillstring in a clockwise direction (as viewed from above

A

Rotary Table

14
Q

Consists of three or more steel wedges that are hinged together, forming a near circle around the drillpipe;

A

Slips

14
Q

On the drillpipe side (inside surface), the slips are fitted with replaceable, hardened tool steel teeth that embed slightly into the side of the pipe.

18
Q

A drillstring turning device

A

Top Drive or Power Swivel

19
Q

Radically different from the more conventional rotary table system as it enables drilling to be done with three joint stands instead of single joints of pipe;

A

Top Drive or Power Swivel

20
Q

It enables complete 90’ stands of pipe to be added to the string rather than the conventional 30’ singles.

A

Top Drive or Power Swivel

21
Q

Consists of one or more motors (electric or hydraulic) connected with appropriate gearing to a short section of pipe called a quill, that in turn may be screwed into a saver sub or the drillstring itself

A

Top Drive or Power Swivel

22
Q
