API certified Aluminium solid casing centralizer is one of the necessary conventional casing accessories, casing centralizers can play the role of:
1. Reducing lower casing resistance phenomenon, make the casing down to the designed position.
2. Make casing centralizers centered in the oil well.
3. To reduce the sticking phenomenon to make the annular space hydrostatic pressure balanced.
4. Reduce channeling, improve the mud replacement efficiency, thus improve the cementing quality.
Function:
Take casing to designed position by reducing sticking while casing going down.
Let the casing pipe center on the well all the way.
Balance liquid pressure in annular space by reducing adhesion phenomenon.
Improving replacing ratio of mud and boosting cementing quality by reducing channeling effect
