Function

TO REPRODUCE SOMETHING, IN A REDUCED FORMAT, FOR DISPLAY OR INSTRUCTIONAL PURPOSES. THIS MODEL ILLUSTRATES THE PHYSICAL LAYOUT OF, AND OPERATIONS CONDUCTED ON, AN OIL DRILLING PLATFORM.

Technical

A ROTARY DRILLING RIG TURNS (ROTATES) THE BIT ON THE BOTTOM TO DRILL: LENGTHS OF PIPE EXTEND THE TOTAL LENGTH OF THE DRILLING SHAFT, AND SOME OF THEIR WEIGHT IS ALLOWED TO PRESS DOWN ON THE BIT IN ORDER TO IMPROVE THE ACTION OF THE BIT'S TEETH OR CUTTERS. FLUID IS CIRCULATED WHILE THE BIT DRILLS: IT FLOWS OUT OF THE BIT AND PICKS UP CUTTINGS, WHICH IT CARRIES UP TO THE SURFACE, FOR REMOVAL. A PUMP RECIRCULATES THE CLEAN FLUID BACK DOWN THE PIPE CONSTANTLY, SO WORKERS DO NOT NEED TO STOP DRILLING IN ORDER TO REMOVE CUTTINGS. (REF. 2)
