Type: oil drill bit
Applicable rock stratum: suitable for medium hard stratum.
Specification parameter: 8 1 / 2 "- 17 1 / 2" API reg
Product details: for medium hard formation, under the premise of optimizing crown profile, high-performance diamond composite chips with good wear resistance, strong impact resistance and good thermal stability are adopted, and the force balance and maximum stress point are analyzed in terms of tooth arrangement to improve the service life of bit. Optimize hydraulic design and improve cooling effect.
