Product Description
Thermoplastic casing composite centralizer


Casing centralizer is one of the necessary conventional casing accessories, upon well operationscompletion, the rational use of casing centralizer can play the role of: 
Reducing lower casing resistance phenomenon, making the casing smoothly down to the design position; 

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. 

Applications: 

Horizontal wells
Deviated wells

Features: 

Available with straight blade centralizer and spiral blade centralizer
Cast steel, cast aluminum and light weight casing rigid centralizer are available
Easy to install
Can move on casing freely, also can be fixed on casing by tighten screws.
