Bit Connection 7 5/8"
IADC Code: S423
Blade Count 6pcs
Primary Cutter 19mm
Nozzles 8pcs
Junk Slot Area (in2) 80.12
Bit Rotary Speed (rpm) 60~260
Weight-On-Bit (KN) 30~160
Flow Rate (lps) 40~70
Application
Medium hard formation of high resist compressiion strength, and have hard interlayers, such as argilite, sandstone, limestone and so on.
Feature
Balanced force design of spiral blades endows the bits with good orientation,little radial vibration as well as ability to increase cutter placement
The reasonable layout of patented PDC cutters in various structures at different locations endows the bits with strong aggressiveness and anti-abrasiveness
Strong aggressiveness allows the bits high ROP
The simulation technology of dynamic flow field are used in hydraulic design to optimize down-hole flow field,beneficial to improve clearance speed and anti-balling simultaneously
