Fixed Diameter Hole Openers are designed for use in soft clays and shales to medium-hard shales and limestones. It is particularly effective in sticky formations where balling problems are encountered. Three jets with replaceable nozzles continuously clean the tool’s cutting structure, clearing debris buildup and increasing penetration.
The gear wheel of a roller reamer is mainly used in the following scenarios: - Oil and gas well drilling: Installed on the roller reamer, it helps transmit torque during the drilling process, enabling the reamer to rotate smoothly, expand the borehole, and maintain the wellbore diameter to ensure the normal progress of drilling operations. - Underground construction engineering: Applied in underground projects such as tunnel boring, it assists the reamer in cutting and reaming the stratum, improving construction efficiency, and ensuring the stability and accuracy of the borehole.
Drilling Roller Reamers are designed for reaming and stabilization in any type of formation.All parts of the tool are made of special alloy steel and heat treated for hardness.Drilling crews can easily replace any part in the field without using any special tools.
