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.
