PRODUCT DESCRIPTION
PDC cutters different features are selected and bit profile design is optimized to suit different drilling applications in different formations to satisfy different requirements when drilling soft to medium hard formations without sulfuretted hydrogen well section.
1. Drill bit with an optimized short parabolic profile adapted to soft to the medium soft homogeneous formation. 2. The involute asymmetric helix blade is designed to make the drill bit more stable. 3. Main and auxiliary cutting structure design, improve the life of the drill bit. 4. Bottom flow field simulation (CFD) hydraulic balance design, more conducive to drill bit cooling cleaning and chip removal.
5. High-performance composite sheet combination to improve the life of the drill bit.
