Longer Life Wear Resistance Pdc Hard Rock Drill Drag Bits For Geological Exploration
Diamond composite (PDC) bit, with diamond composite as the main cutting element, adopts the principle of scraping and shearing to carry out rock crushing, which is suitable for drilling in soft to medium hard stratum, and has better advantages in overcoming incomplete stratum drilling.By making full use of the high wear resistance and high impact resistance of diamond composite bit, it has the advantages of high life, high aging and high cost performance.
Functions and features
1. Application: soft to medium hard formation, mudstone, sandstone and intercalated limestone, reinforced and super-strong composite bit can be applied to super hard formation.Motor or rotary drill is available.The special design makes the stability of the drilling tool excellent.
2. Simple motor orientation: the bit adopts special cutting structure and straight blade design, which makes the bit work smoothly and the tool surface swing less when it slides into the hole.While rotary drilling can maintain a high rate of penetration.Thus, these design combinations ensure that their use effect is unmatched.
3. Highly smoothed cutting teeth: highly smoothed cutting teeth can reduce the friction resistance during cutting, quickly remove debris, significantly improve the cutting efficiency and thus improve ROP.
4. Stability features: the design features of different stability keep the drill bit in a stable state for most of the time when it works in the well, which can inhibit the vibration damage to the drill bit caused by BHA, operation or/and formation
