Look at the diagram of rotary rig。Notice the string。This*is made up of(注2) 'joints' or 'singles'。 Each joint or single is a hollow section of pipe, *30ft。Long(注3)。 The string is made up of *a number of these singles(注4), all joined together。 The bit is connected to the bottom of the string。 At the top of the string there is a special pipe called the 'kelly'。The kelly isn't ronud, but hexagonal。 it fits into(注5) a hexagonal hole in the rotary table。The rotar
