The reamer mainly consists of four or more cones. Cutting Structure
with premium tungsten carbide hardfacing or premium tungsten carbide
insert of formulas and new techniques is utilized, and increases wear-resistance capability of reamer. The pilot is tricone bit.
Seal and Lubrication
High performance HNBR O-ring for bearing seal and advanced grease
for lubrication.
Product Application
It is suitable for the large size well, mining and infrastructure applications.
Recommended Drilling Parameter
IADC | WOB (KN/mm) | RPM (r/min) | Applicable Formations | |
517/537 | 0.4~1.0 | 120~60 | Soft formations with low compressive strength and high drillability, such as mudstone, gypsum, salt, soft limestone, etc. | |
617 | 0.45~1.1 | 90~50 | Medium hard formation with high compress strength, such as hard shale, limestone, andstone, dolomite. etc | |
