Bi-center Bit
Overview ofbi center bit
This type of bi center drill bitmainly used for medium to medium-hard compressive and abrasive formation, it has medium and high-density parabolic crown and heavy cutters density for the bit has good impact resistance and anti-abrasive, high wear-resistant diamond gauge, the bit has a longer service life.
In directional applications, Bi-centre bit performance usually presents performance challenges in terms of efficiency versus power availability and dynamic issues.
GREAT designed the bi-center bit to enlarge the wellbore diameter, to replace under reaming, to help control rouble zones and for expandable tubular.
The Advantage of Bi-center Bit
Our Bi-center bit is one piece body, you will never worry broken.
We can adjust the bi-center diameter according to your casing diameter. Generally speaking, the bigger pilot bit has smaller reaming size. The smaller pilot bit has a bigger reaming size.
GREAT's casing protection features cutting structure that provides a reliable way to drill, protecting both the cutting structure inside the casing and the casing itself.
During the design process, the pilot and reamer cutting structure are force balanced as a single unit. This provides increased drilling efficiencies in both vertical and deviated wells.
