Likewise, what are some primary advantages of using a top drive rotary system? The two major advantages of a top-drive drilling rig are: the ability to handle multiple joints (two or three joints) of drill pipe at one time during connecting/unconnecting operations. the ability to rotate the drill pipe while tripping into or out of the wellbore to avoid Stuck Pipe during tripping operations.
Simply so, how does a top drive system work?
Used to rotate the drill string during the drilling process, the top drive is a motor that is suspended from the derrick, or mast, of the rig. These power swivels boast at least 1,000 horsepower that turn a shaft to which the drill string is screwed.
