PDC Bit
Application
♦ | PDC drill bit is mainly used to drill Oil well, gas well, water well, etc. |
♦ | We design and produce specified PDC bit with good performance for each soft, medium and hard formation. |
♦ | Clay stone/lignite/siltstone/sands: We design 3-5 blades with low density cutter placement,large slot. Low cost, high speed. |
♦ | Mudstone: We have experience to design suitable blades shape and cutter direction to get high drill speed and stable drill. |
♦ | Gravel/limestone/shale/clay stone/tuff: Round crown and reasonable cutter direction. Drill smoothly in good speed. |
Introduction
♦ | 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. |
♦ | Raw materials: Alloy steel with a special treatment, achieve better mechanical properties (Rp0, 2: 1200MPa; Rm: 1100 MPa) |
♦ | 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.) |
♦ | The scientific drilling dynamic equilibrium design and hydraulic balance design make the drilling process smoother. |
♦ | Authoritative API standard and ISO certification, quality and service will be better ensured. |
