Overview of Bi-center Bit
This type of bi center mainly 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 i***ct resistance and anti-abrasive, high wear-resistant diamond gauge, the bi-center drill 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 bicenter bit to enlarge the wellbore diameter, to replace under reaming, to help control rouble zones and for expandable tubular.
Bi-center Bit Design
We designed this bi-center bits with close attention to hydraulic optimization to improve chip removal and ensure effective tool cooling. In addition to the improved hydraulic configuration, the cutting configuration was carefully studied to ensure that it is both effective and balanced - not only on conventional components but also when used in combination with a bent-case motor. This design concept of bi center bitscombined with GREAT's wide range of PDC cutters grades and geometries results in a bi-center drill with excellent drilling performance.

The Advantage of Bi-center Bit
Our Bi-center bit is one piece body, you will never worry about broken.
Cangzhou Great Drill Bits Co.,Ltd. can adjust the bi-center diameter according to your casing diameter. Generally speaking, the bigger pilot bit has a smaller reaming size. The smaller pilot bit has a bigger reaming size. |
