| PDC DrillBit | ||||||
| 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 designedtooth reduce the cutting edge wear & increase life (no repair life up to8300M/pc). | |||||
| • | The unique parabolic crown-shaped design andtooth balance design keeps smooth drilling under high speed. (Speeds up to30~40m/h.) | |||||
| • | Raw materials: Alloy steel with a specialtreatment, achieve better mechanical properties (Rp0, 2: 1200MPa; Rm: 1100MPa) | |||||
| • | Steel body with hardening tungstencarbide surface(WC),make the drill bit both high strength and very strongabrasion resistance. | |||||
| • | Dedicated PDC cutter can improve thelife and shield the risk of complex formation drill not passed. | |||||
| • | The scientific drilling dynamicequilibrium design and hydraulic balance design make the drilling process moresmooth. | |||||
| • | Authoritative API standard and ISOcertification, quality and service will be better ensured. | |||||
