ISO
Simple structure, flexible piston and good tightness.
Small OD makes, not easy to be blocked.
It is mainly composed of main body, slip centralizer bush, piston, and self-blocking mechanical.
1. Application
Casing centralizer is mainly used for centralizing of the well which needs 4〞casing because of the deformation of *1/2″casing and sidetracking well.
2. Structure and Work Principle:
Casing centralizer is mainly composed of main body, slip centralizer bush, piston, and self-blocking mechanism and so on.
FKZ***4 casing centralizer is put in the downhole with 4〞casing. Then give pressure after well completion. When the pressure is up to ****2Mpa, all the centralizers begin to work. Centralizer slip is against the inwall of 5 1／2〞casing or open hole in order to support and centralize  4〞casing. Because of the self-block mechanism, slip can be against casing inwall after pressure released until well completion. 4〞casing can be always centralized in the middle.
