Specifications
oilfield pdc drill bit
1. Hard-facing
2. Better cutting capability
3. Oil drilling
4. Good erosion-resistant.
Fratures:
1. Cutting structure is force balanced and bit blade is asymmetrically designed so that the load on bit is balanced that resulting better stablity of the bit.
2. Main cutter is high performance PDC cutter to insure service life of the bit while improving ROP.
3. Cutter exposure is optimized to insure the bit can achieve higher ROP is soft to medium formations.
4. Shock absorbers are designed to make the bit capable of drilling through formations with hard strigers.
5. Hydraulic systems of the bit is optimized using dynamic flow pattern simulation technology enhance cleaning and cooling effects of the bit to effectively prevent bit from balling.

| Applications: | ||||||
| • | Used in many fields such as : Oil well, gas well, water well, etc. | |||||
| • | Formation: Suit for drilling medium, medium-soft and midium-hard formations. | |||||
| • | Well type: Suit for helical well, inclined well, lateral well. | |||||
Performance: | ||||||
| • | Low torque spiral design and software designed tooth reduce the cutting edge wear & increase life (no repair life up to 8300M/pc). | |||||
| • | The unique parabolic crown-shaped design and tooth balance design keeps smooth drilling under high speed. (Speeds up to 30~40m/h.) | |||||
| • | Raw materials: Alloy steel with a special treatment, achieve better mechanical properties (Rp0, 2: 1200MPa; Rm: 1100 MPa) | |||||
| • | Steel body with hardening tungsten carbide surface(WC),make the drill bit both high strength and very strong abrasion resistance. | |||||
| • | Dedicated PDC cutter can improve the life and shield the risk of complex formation drill not passed. | |||||
| • | The scientific drilling dynamic equilibrium design and hydraulic balance design make the drilling process more smooth. | |||||
| • | Authoritative API standard and ISO certification, quality and service will be better ensured. | |||||
