Casing Centralizers – API 10D Standard for Oil & Gas Cementing

Casing centralizers, also known as drilling ,centralizer,, are important cementing tools to position the casing uniformly inside the wellbore to offer a more uniform distribution of cement slurry around the casing. They can also reduce the friction between casing and wellbore and keep the casing from hitting the wellbore walls.

The centralizers on a casing string are used to provide clearance between the, casing, and the wall of the hole. The clearance is called standoff. The major function of the, casing centralizer, is to centralize the, casing, in the hole and to prevent it from lying against the wall, thus providing a reasonable uniform cement layer around the casing.

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.
