Roller Casing Centralizers

Size: 13-3/8”*16”, 9-5/8”*12-1/4”, 7”*9-1/2”, 5-1/2”*8-1/2”

Features:

1. Reduce the friction force between the casing and the borehole wall by changing the friction between the casing and the borehole from sliding friction to rolling friction, and help to run the casings to the reserved position successfully. 

2. The roller can reduce the impact of the borehole wall on the spiral centralizer during running casing when the hole diameter is irregular.

3. The spiral centralizer can make the mud and the slurry form bumpy flow to wash false filter cakes out and improve displacement efficiency, the bonding strength of the slurry and the borehole wall, and cementing quality during cementing.

4. The roller rigid casing centralizers are adopted to be used in the inclined section or the horizontal section.
