7" Spiral Vane Roller Casing Centralizer For Oil Water Well

Roller centralizers are mainly used for big high Roller, high deviated wells and horizontal wells, to centre 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.

Features

The roller centralizers are designed in rigid body with straight or spiral blades.
Rollers provide low drag to get casing, liners, or screens to bottom successfully with reduced rig time and costs.
Minimal roller-contact area reduces the risk of differential sticking and provides optimal standoff to increased operational efficiency.
The roller centralizer is used in deviated and horizontal wells.
