Roller centralizers are mainly used for high deviated wells and horizontal wells to center casings. Roller Centralizers can also remove wellbore cake and improve mud replacement efficiency etc. Roller Centralizers provide superior wear resistance and have been proven to remain functional throughout the life of the well and can aid in casing/tubing retrieval.
- Reducing the friction resistance.
- Increased casing depth
- Ensure the casing centered
- Improving liquid flow characteristics
- Improve grouting condition
