Feature:
suitable for soft to medium hard formations
medium parabolic profile and scientific cutter density
higher quality PDC cutter, which ensure longer bit life for the formations with interbed layers.
optimized hydraulies desin,which improve the bit clean ability and avoiding balling.
Oilfield pdc bit for sandstone drilling characteristics:
1.Uses outline optimization design, adapts in different strata.
2.Short parabolic crown, cutting force balance design structure, spiral knife-wing,balance the bit
force,improve impact resistance.
3.Uses the dynamic flow field technique of simulation, optimizes the drill bit water power design, strengthens the drill bit clean, cooling capacity and prevents the drill bit balling.
4.Using high performance compound piece combination , enhances the bit life.
