Product Application
It can receive higher WOB and faster rotary speed than conventional roller bearing bits .It is suitable for high RPM applications.
Recommended Drilling Parameters
IADC WOB(kN/mm)(bit dia) RPM(r/min) Applicable Formations
115 0.3--0.75 200--80 Very soft formations with low compressive strength and high drillability,such as clay,mudstone,chalk ,etc.
125 0.3--0.85 200--80 Soft formations with low compressive strength and
high drillability,such as mudstone,gypsum ,salt,soft shale,soft limestone,etc.
135 0.3--0.95 180--80 Soft to medium soft formations with low compressive strength and high drillability.such as medium soft shale,
hard gypsum,medium soft limestone,medium soft sandstone,soft formation with harder interbeds,etc.
215 0.35--0.75 180--80 Medium formations with high compressive strength ,
such as medium soft shale,hard gypsum,medium soft
limestone,medium soft sandstone,soft formation with
harder interbeds ,etc.
