Roller reamers are hydraulically powered and rotate at high speeds, using roller cutters to scrape the hole-walls as it moves. The roller knives shear the rock ahead of the bit, creating a smooth surface for drilling fluid to travel through. As roller reamers turn, they also remove any debris in the hole, keeping it clean for the drill bit.
The roller reamer body is connected to the drill pipe by a threaded connection and uses drilling fluid to cool and lubricate the roller cutters. The roller knives are mounted on bearings that allow them to spin freely as they come into contact with the hole wall.
There are many benefits that come with using roller reamers during the drilling process. Some of the most notable benefits include:
Reduced hole-wall damage
Improved drilling fluid circulation
Increased rate of penetration
Reduced wear on drill bits and other drilling tools
Enhanced safety throughout the drilling process
