1 The force balance design makes the drills have a good orientation, and it is suitable for directional drilling with the use of downhole motors and has small radial vibration;

2 The reasonable arrangement of patented PDC composite discs with different structures in different positions of the drill bit makes the bit more aggressive and anti-abrasive;

3 aggressive design allows the drill bit to obtain high penetration rate;

4 The dynamic flow field simulation technology is applied to hydraulic design to optimize the flow field at the bottom of the well, which helps to increase the chip removal speed and mud prevention.
