Different types of composite cutters can be selected based on the hardness and abrasiveness of the coring formation.
A force-balanced design ensures greater stability during the coring process, resulting in more uniform core samples.
The optimized overall crown shape features wider flow channels to prevent annular space blockages, enabling the drill bit to handle a variety of complex formations and significantly improving core recovery efficiency.
Different types of composite bits can be selected based on the hardness and abrasiveness of the core-taking formation.
Employing a force-balanced design, the drill bit achieves greater stability during core extraction, resulting in more uniform core samples.
Optimizing the overall crown design and widening the flow channels help prevent annular clogging, making it adaptable to various complex formations and improving core-taking efficiency.
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”.
