Dec. 01, 2018
The primary job of Casing Centralizers is to effectively spread the cement in the well casing. There are various types of Casing Centralizers used in the industry, but these are the four primary types of centralizers:
Bow-Spring Centralizer – This type of centralizer is a bow-shaped metal strip used to centralize the casing in a borehole so as to improve the efficiency of cementing.
Rigid Centralizer – This type of centralizer is built using steel or cast iron and works well with the deviated wellbores. It is not as effective as bow-spring centralizers.
Semi-Rigid Centralizer – This type of centralizer is made from double-crested bows that have both the features of bow springs and rigid centralizers.
Mold on Centralizer – This type of centralizer is made from carbon fiber ceramic materials and can be used directly to the casing surface.
