a. Take casing to designed position by reducing sticking while casing going down.
b. Centralize casing in well.
c. Balance liquid pressure in annular space by reducing adhesion phenomenon.
d. Improving replacing ratio of mud and boosting cementing quality by reducing channeling effect.
e. Restoring force of double-bow casing centralizer is higher than single-bow casing centralizer's, and centralization performance is stronger.

9) Features of Casing Pipe Spring Centralizer:

a. Designed for high restoring force and low starting&running force
b. Undergo special coating process to prevent from rust
c. For hinged bow spring casing centralizers, end collars are designed with self-locking action, which are easy to assemble and can be shipped in half assembled condition for less shipping and storage costs.
