Information

The centralizer, also known as the guide, is a centralizer that is installed on the outer surface of the casing to ensure that the running casing string is located in the center of the wellbore. The use of centralizers in oil and gas drilling and production can improve the working stability of the drill bit, thereby prolonging the service life of the drill bit. Common centralizers mainly include rigid centralizers, integral centralizers, roller centralizers, hinge centralizers, etc.

Rigid centralizer china

According to the material forming form, the integral centralizer can be divided into: tube integral stamping type and sheet rolling stamping type.
The 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 set screw or a fixing ring.
The rollers on the rib of the roller centralizer can roll when running into the casing, reducing the running resistance, making the casing easier to run, improving the displacement efficiency and improving the cementing quality.
The hinged elastic casing centralizer uses high-strength springs to support the casing to center the casing and improve the cementing quality.
