The centralizer, also known as the centralizer, is a centralizing frame installed on the outer surface of the casing to ensure that the casing string to be run is located in the center of the wellbore. The use of centralizers in oil and gas drilling can improve the working stability of the drill bit, thereby prolonging the service life of the drill bit. Common centralizers include Stamped Rigid Centralizer, integral centralizer, roller centralizer, hinge centralizer, etc. Let's take a look at Stamped Rigid Centralizer in detail. The Stamped Rigid Centralizer can freely rotate and slide up and down on the casing, or it can be fixed to a certain part of the casing with a fixing screw or a fixing ring.

Features of Stamped Rigid Centralizer 1. There are two types of straight ribs and spiral ribs; 2. Cast steel and cast aluminum materials are available; 3. It can be used in vertical wells, highly deviated wells and horizontal wells.
The Stamped Rigid Centralizer has obvious advantages compared with the elastic centralizer. If the casing rotation is required to improve the displacement efficiency during cement injection in a vertical well, then the Stamped Rigid Centralizer is the best choice. In deviated and horizontal wells, the leaf spring centralizer can no longer support the heavy casing string. If the casing in the cement-sealed section is required to rotate, Stamped Rigid Centralizer is the only choice.
