Oilfield Composite  Centralizer Casing / oilfield rigid centralizer

Rigid casing centralizer is used in deviated wells and horizontal wells. There are several blades on the rigid centralizer that can keep casing from contacting the wellbore wall.

Roller rigid centralizer which is most suitable for highly deviated wells and horizontal wells has two or three rollers in each blade. It can change slipping friction to rolling friction, so it greatly reduces the friction between casing and wellbore wall and let casing go to desired position smoothly.

Horizontal wells
Deviated wells
