Geological drilling impregnated diamond core drill bits
Advanges:
1. Balance design makes the bit has good guidance, fit downhole motor used in directional drilling, with smaller radial vibration;
2. Different structure of patent PDC composite in different position of reasonable decorate bit bit strong aggressive and abrasive resistance;
3. Strong offensive design make bit can obtain the high rate of penetration;
4. Dynamic flow field simulation technique is applied to hydraulic design, make the bottom hole flow field optimization, to improve chip removal rate and the balling.applied to hydraulic design, make the bottom hole flow field optimization, to improve chip removal rate and the
