Goldman PDC DRILL BITS : |
|||||||
|
Matrix-body |
Advantage : Matrix body PDC bits are commonly preferred over steel-body bits for environments in which body erosion is likely to cause a bit to fail . For diamond-impregnated bits ,only matrix-body construction can be used . |
||||||
|
Steel-body |
Advantage : High resistance to impact loading Considerably stronger than matrix bodies Easily be rebuilt a number of times Worn or damaged cutters can be replaced rather easily Particular advantage for operators in low-cost drilling environments
|
||||||
|
|
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. |
|||||||
|
The scientific drilling dynamic equilibrium design and hydraulic balance design make the drilling process more smooth |
|||||||
|
Speeds up to 30~40m/h Authoritative API standard and ISO certification, quality and service will be better ensured |
|||||||
The main structrue features:
--Tungsten carbide matrix PDC possesses high wear resistance and impact resistance.
--Parabolic crown profile and maximizes junk slot area can clean bit better, and prolong the bit working life.
--Applying hydraulics balance design , 5 renewal nozzles and reasonable nozzles locating angle can gain ideal fluid field in wellbottom , fully clean and cool cutter , and prolong the cutter working life.
--Non-symmetry blade arrangement enhances drilling well balance.
--Optimization for cutter shape ,slant angle , cutter numbers prolong the cutter working life in combination with high quality PDC cutter, and improve ROP and drilling efficiency.
--It can be used on rotary or down hole motor.
--High HIS is recommended.
