TORQUE REDUCTION SUB
TORQUE REDUCTION SUB
TECHNICAL SUMMARY
Torque reduction sub is to reduce the excessive torque generated by drilling in short radius horizontal section and large angle well section. According to its structural components, the torque reduction sub is divided into: mandrel body, upper and lower sliding bearings, slip spiral inner sleeve, straight rib outer sleeve, stop collar etc.
Torque reduction sub is mainly connected between short radius horizontal section and large angle well section, propose to connect a torque reduction sub by every 60ft, it can reduce 25%-35% torque after using this tool, it’s slip spiral inner sleeve, straight rib outer sleeve and body mandrel are relatively in non-rotating condition.

FEATURES
1. Reduce drill string wear and fatigue
2. Minimizes torque and drag
3. Minimizes casing wear
4. Increase ROP
5. Dampens vibration
6. Enhances drilling efficiency
