Roller reamer
Roller reamers are employed in boring operations for the oil & gas industry.
The main function of roller reamers cut earth formations to enlarge the borehole to the desirable size during well drilling operation, which may be the original size of the drill bit in the case where the drill bit wears to be under-gauged. However, even for new drill bits, roller reamers are employed to cut formations because the bit does not always drill a true bore hole and because of slight lateral shifting which is inherent in the drilling operation, which shifting leaves ledges and other distortions.
Additionally, the second function of a roller reamer is to keep the drill stem in the center of the hole at the specific position of placement of the roller-reamer. In providing such a function, a reamer is often referred to as a stabilizer. Maintaining the drill stem centered has many beneficial effects, its primary one being minimizing unintentional hole-angle directional drilling.
