Function：
Directly integrated into the drill string, this tool:
1.Eliminates Casing Wear:
Diverts contact points away from drill pipe tool joints
Prevents direct metal-to-casing abrasion
2.Reduces Drilling Torque:
Converts friction through rotational sliding between the high-energy rubber sleeve and mandrel
3.Extends Drill String Life:
Lowers fatigue stress by 35-50%
Minimizes casing wear rates by ≥80% (per API TR 7PER15K tests)
Applications：
1.High-Angle & Horizontal Wells: Manages side loads >15,000 lbf
2.Deep/Extended-Reach Wells: Reduces torque by 15-25%
3.Sidetrack Drilling: Prevents wear in build sections
4.ERD (Extended Reach Drilling): Enables longer laterals
Key Specifications：
1.Connection Types: API NC50, 6-5/8" REG, 7-5/8" REG (customizable)
2.Temp Rating: -40°C to 175°C (H2S/CO₂ resistant)
3.Max RPM: 250
4.OD Range: 8-3/4" to 12-1/4"
5.Load Capacity: Static ≤80,000 lbf / Dynamic ≤45,000 lbf
