What is a rigid casing centralizer

2021 03/05

Casing centralizer is a cementing tool device installed on the drilling casing string to make the casing string in the wellbore.

Compared with other cementing tool accessories,casing centralizer has the characteristics of long life,simple structure,convenient operation and low cost.

The material of the Rigid Casing Centralizer is mainly cast steel.Compared with the elastic centralizer,the rigidity of the rigid centralizer is higher,and the centralizer fins are easy to cause damage to the wellbore wall.In addition,when the centralizer is stuck,it is not conducive to the rotation of the casing,which affects the cementing of the rotary liner and the implementation of the cementing process of the rotary casing.

However,in some specific Wells,Rigid Casing Centralizers are indispensable.
