8 3/4'' five blades pdc drill bits
Application
1,Suit for drilling medium to medium-hard formations.
2,Evolute asymmetrical blade cutter design and balanced bit load so that bit whirl is prevented.
3,Composite gage protection and low torque design improve rate of penetration.
4,CFD hydraulic balance design results in better bit cleaning and cutting removal .
5,Combined utilization of high performance PDC compacts significantly prolongs bit life
6,Higher nozzle counts and/or fixed ports to best serve cleaning,cooling and cuttings evacuation requirements with available hydraulic flows.Allows for higher flow rates with minimal increase in pump pressure.
Feature:Diamonds are impregnated in the matrix behind the PDC cutters
Benefit:Increased footage drilled in abrasive applications.
Advantage:
1.Optimized short parabolic profile,suitable for drilling soft to medium soft homogeneous formations.
2.Asymmetrical evolute spiral blade cutter placement makes the bit more stable during drilling.
3.Prlmary and secondary cutting structure extends bit life.
4.CFD hydraulic blance design results in nbetter bit cleanding1 and cutting removal.
5.Combined utilization of high performance PDC compacts significantly prolongs bit life.
