Product Description
Casing Centralizer
Casing Centralizer is a device used to place the casing at the center of the hole so as to improve the efficiency of the cementing. It is an important device because if the Casing Centralizer touches the formation at any part of the hole, then cement slurry does not pass through the area of the contact resulting in a poor cementing job.
Casing Centralizers Types:
There are various types of Casing Centralizers used in the oil and gas industry, but these are the 2 primary types of centralizers:bow spring centralizers and rigid centralizers.
(If As per action form, it can be divided into Bow Spring casing centralizer, rigid casing centralizer and semi-rigid centralizer.)
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.
Rigid centralizers are slightly smaller than the well bore.
They are more commonly used in deviated or horizontal well bores where the weight of the casing string would cause a bow spring centralizer to experience eccentric compression which could jeopardize the seal.
(The rigid casing centralizer can be divided into ordinary rigid centralizer and roller rigid centralizer.)

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.
Bow spring centralizers are slightly larger in diameter than the well bore, so they become slightly compressed when inserted into the well bore. They are often used in vertical wells as there is near zero deviance in annular space about the tool.
(As per structure of the righting strip,the elastic centralizer can be divided into single bow centralizer and a double bow centralizer.)
