DrawWorks Application: Explosion Proof Encoders

The weight of the drill string on a drilling rig is carried by a traveling block and tackle arrangement. This block and tackle is operated by a winch known as a DrawWorks – a very critical piece of equipment. Drill pipe is carried by the Top Drive which rotates and descends into the hole as the drill bit grinds away the rock. Measuring the amount that the traveling block has traveled indicates how much length of pipe is down the hole. This informs the drill rig operator if their drilling program is on track and allows them to correlate the expected with the actual rock formations that they are encountering.
