Eccentric Rotating Shoe
Metal body with circulation ports and an eccentric tip secured by a retaining ring.
Advantages
- effective circulation of the flushing fluid;
- eccentric design of the guide section;
- rotation under axial compressive load without initiating circulation;
Specifications
- maximum compressive load: up to 63 tf
- central circulation port diameter: 40 mm
- total circulation port area: 1700 mm²
- bevel angle of the eccentric tip: 60°
- size range: 102/140(146); 114/168(178); 127/178; 168(178, 194)/245
Application area and experience
The rotating shoe is designed for equipping the bottom of casing strings to guide them along the wellbore and protect them from damage during running. To minimize resistance, the eccentric nozzle of the shoe rotates when it abuts the wellbore wall.
