Drill bit design for improved drilling efficiency and reduced vibration
The patent US12071817B2 describes a novel drill bit designed for advancing boreholes, featuring a bit body with a central axis and multiple blades, specifically a first and a second blade. Each blade is equipped with polycrystalline diamond compact (PDC) cutters arranged in pairs, where each pair consists of a cutter on the first blade and a corresponding cutter on the second blade. Notably, the angular distance between the cutters in each pair varies, resulting in different engagement timings with the formation as the drill bit rotates. This design aims to enhance drilling efficiency by optimizing the interaction between the cutters and the material being drilled.
Further details of the drill bit's design include various patterns for the blades, such as sinusoidal, linear, and curved shapes, which may feature concave and convex regions. The first and second blades can exhibit differing waveform patterns, potentially leading to phase shifts in their operation. The arrangement of the blades and the channels separating them is also specified, allowing for a more effective drilling process. Overall, the claims outline a sophisticated approach to drill bit design that seeks to improve performance through innovative cutter arrangements and blade configurations.
