diamond oil drilling bit

PDC oil drilling bits series

(1)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

(2)Short round crown profile

     Force balanced design reduces bit whirl and makes it working stable

     Asymmetrical blade type cutting structure

     Optimized hydraulics enhances bit performance

Suitable for drilling medium soft to medium homogeneous formations 

(3)Medium cone crown, good stability

     Round and scribe TSP stones are arranged alternatively for high penetration rate and long bit life

     Applicable formations: soft to medium hard carbonate or sandstone with medium abrasiveness

(4) Shallow cone crown, with even WOB distribution, good cleaning and long bit life

      Dense placement of staggered cubic, round and scribe TSP stones for high penetration rate in hard formations

      Applicable formations: Medium hard carbonate or sandstone with medium abrasiveness
