The roller reamer is a crucial downhole tool used in oil and gas drilling operations. It serves dual purposes: maintaining borehole size and stabilizing the drill string while drilling through abrasive or challenging formations.
A roller reamer consists of a rugged body equipped with rotating rollers or blocks. These rollers help to ream out irregularities in the borehole wall, reduce vibration, and minimize wear on drill bits. They are especially effective in hard rock formations where hole enlargement or reaming is needed without compromising directional control.
Our roller reamers are available in various sizes to fit hole diameters ranging from 6” to 36”, with replaceable cutter blocks to accommodate different formation types. The body is manufactured from high-strength alloy steel (e.g., AISI 4145H Modified) and treated for excellent impact and fatigue resistance.
We also offer oil pressure sealed designs, ensuring extended bearing life and reduced maintenance requirements. These features make our roller reamers a reliable choice for both conventional and directional drilling applications.
Whether for hole conditioning, stabilization, or vibration control, the roller reamer remains an indispensable tool for efficient and cost-effective drilling.
