Optimize for specialized, tooth-shaped cutters such as pointed and asymmetrical teeth to maximize pre-crushing and repeated grinding, thereby enhancing the composite bit's penetration depth and boosting its overall drilling capability.
Reduce the nose-shoulder rake angle and incorporate a small chamfer design to improve the bit's aggressive cutting performance.
Employ a P2 or P3 medium parabolic crown profile to prevent excessive torque-induced premature failure, ensuring smooth and stable cutting throughout the operation.
Implement a well-designed hydraulic system to enhance rock chip removal efficiency.
Size Range：4 1/2”~12 1/4”.
Preferably use special-shaped teeth such as sharp-pointed ones, as pre-crushing and repeated grinding maximize the composite bit's penetration depth, enhancing the drill bit's cutting capacity.
Reducing the nose-to-shoulder angle, combined with a subtle chamfer design, enhances the overall aggressiveness.
Adopting the P2 and P3 medium parabolic crown designs to prevent excessive torque that could lead to premature failure, ensuring smooth and stable cutting throughout.
Rational hydraulic structure design to enhance cuttings transport capability.
The matrix body PDC bit not only applies the lDS system to optimize the cutter arrangement, hydraulic, and mechanical models but also uses advanced matrix body formulations to ensure the strength of the bit body. The high-precision and high. performance rubber mold guarantees the accuracy of the cutter holes and crown shape of the matrix body PDC bit, meeting the high-quality customization needs of domestic and international customers.
The internal cone features a concave design, reducing the center height of the blade wings and distributing the drilling load more evenly, thereby enhancing stability.
The symmetrical blade wing arrangement widens the blade channel, improving chip-removal efficiency and preventing buildup at the bottom of the wellbore—thus avoiding repeated cutting.
Additionally, the large-angle nozzle bore angle facilitates effective flushing of the well bottom, helping to prevent bit sticking.
The pilot shoe center works in coordination with the reaming body center, while the arc length around the reaming body is precisely controlled by the wing angles, ensuring stable wellbore enlargement.
An IDS intelligent tooth-placement design is employed to meet the principle of minimum bottomhole force balance, enabling the drill bit to achieve smooth cutting at the bottom of the well.
Equally spaced and narrowly designed cutting wings maximize the flushing area of the flow channels, significantly enhancing overall rock-breaking efficiency.
The gauge protection layer is made from TSP polycrystalline material and features an anti-rotation design, which reduces vibration-induced wear and extends the drill bit's service life.
Size Range：3 1/4”~26”.
