Casting Centralizer

Best Casting Centralizer in China

A centralizer is a mechanical device that keeps the good casing from touching the sides of the wellbore. This gives the drilling team a complete 360-degree space around the casing for applying cement or other completion materials. In the drilling and cementing industry, there are 3 kinds of centralizers used.

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

All of them are used in Horizontal wells and Deviated wells

What is casting centralzier?

Casing a centralizer as a cementing tool is applied in vertical, deviated and horizontal wells to centralize casing for improving the cementing quality.
The cement could be concreted firmed between casing and borehole wall.
It can be installed on a casing joint or any position working with a stop collar for centralizing.

What is the type of centralzier?

1-As per action form, it can be divided into Bow Spring casing centralizer, rigid casing centralizer, and semi-rigid centralizer.
2-As per the structure of the righting strip, the elastic centralizer can be divided into a single bow centralizer and a double bow centralizer.
3-The rigid casing centralizer can be divided into ordinary rigid centralizer and roller rigid centralizer
