What are the functions and structural characteristics of tubing centralizer?

I.Overview:

Tubing centralizers are used in large dogleg deviated and vertical Wells to avoid or reduce wear between light tubing and casing.

Two,use:

The tubing centralizer is mainly used for tubing centralizer in inclined Wells of oil and water Wells.
III.Structure:

The tubing centralizer is mainly composed of a body and a rotary centralizer.

IV.Features:

1.Machine-produced tubing centralizer can ensure the tubing is centered and reduce eccentric wear.

2.Simple structure,flexible rotation,small friction,good righting effect.

3.Use on both ends of the packer to reduce the friction damage of the wellbore wall to the rubber cylinder of the packer and extend the service life of the packer.
