The Layout Of Different Patented PDC Cutters Enhances The Capability To Drill Hard Stringers
CFD Technology Is Applied In Optimizing Hydraulic Efficiency.
Hard alloy hydraulic sleeve are installed to increase the service life of the hydraulic components of the bit. The use of bits without hydraulic nozzles may cause the sleeves to fall to the bottom of the well and lead to wear of the cutters.
This is a 6blade with 1613mm cutters PDC bit, which used for vertical drilling. After optimized the design, this bit has achieved 1.5 times higher ROP than our competitors.
