Definition from
Petex:
the heavy square or hexagonal steel member suspended from the swivel through the rotary table and connected to the topmost joint of drill pipe to turn the drill stem as the rotary table turns.
Example sentences:
Ten metre pipe lengths are stored temporarily in the mouse hole while the kelly bar is swung across to screw into the pipe threads. When not in use, the kelly and swivel are secured in the rat hole. (The Petroleum Institute Training Service)
The kelly has sides so that it can be gripped and turned. Turning the kelly turns all the pipe in the hole and drills the hole. (Foster Learning Inc. )
Drilling fluid, better known as drilling mud, is circulated through the kelly and the drill string by means of pipes and flexible hose connecting the drilling fluid or mud pumps and a swivel device attached to the upper end of the kelly. (Kansas Geological Survey)

kelly-stang
Definition from
Miljøstyrelsen:
Firkantet eller sekskantet borestang monteret øverst på borestammen.
Example sentences:
Et tidligere anvendt system til overføring af rotation bestod af en firkantet eller sekskantet borestang - en såkaldt Kelly-stang - monteret øverst på borestammen. Denne kunne vandre lodret gennem et drejebord med en central gennemgang med tværsnit svarende til Kellystangens. Rotationen overføres via drejebordet til Kelly-stangen og dermed til borestammen, jf. Figur 18. Borestammen med mejsel blev holdt oppe af en wire fastgjort til toppen af kellystangen, som via en topskive i boretårnet var forbundet til et wirespil. Wiren blev firet af spillet i takt med uddybningen af boringen. Dette princip blev især anvendt inden for olieindustrien og anvendes stadig i nogen udstrækning. (Miljøstyrelsen)
