PDC Oil Drilling Bits
Optimized short parabolic profile, suitable for drilling soft to medium soft homogeneous formations
Asymmetrical evolute spiral blade cutter placement makes the bit more stable during drilling
Primary and secondary cutting structure extends bit life
CFD hydraulic balance design results in better bit cleaning and cutting removal
Combined utilization of high performance PDC compacts significantly prolongs bit life
Application Of The PDC Bits
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
