1.Force balance design makes the drill bit has good guidance quality, applicable to directional well drilling with downhole motors, having smaller radial vibration.
2.Reasonable arrangement with different structure of patent PDC composite on different positions makes the drill bit more aggressive and with better anti-abrasive quality.
3.High density tooth arrangement enhances the aggressivity and abrasive resistance of the drill bit when used in medium hard to hard formations.
4.Dynamic flow field simulation technology used in hydraulic design enables the bottomhole flow field optimization, improves the speed of chip removal and avoids bit balling.
