Enlarge Borehole Reamer, Downhole Roller Reamer, 5 7/8''~28''​

Roller reamer is designed for various reaming operation. It can be used in hard formation or abrasive formation in order to keep the standard hole size. When the bit size is under the standard size, it can ream the well bottom size to standard hole size. Whether drilling the vertical well or directional well, it can make the bit or casing come into the normal hole size. The features of roller reamer are small frictional resistance with well wall, strong abrasive resistance and long life.

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.
