Rigid Centralizer

 

Rigid Casing Centralizer

 

Regular rigid casing centralizers:

 

Size: 20"*26", 16"*20", 13-3/8" *17-1/2", 10-3/4"*14-3/4", 9-5/8"*12-1/4", 8-5/8"*10-5/8", 7-5/8"*9-1/2", 7"*9-1/2", 7"*8-1/2", 6-5/8"*8-1/2", 5-1/2"*8-1/2", 5"*8-1/2", 4-1/2"*6-1/8", 4"*5-7/8"

We can supply various rigid casing centralizers according to casing and wellbores for users.

 

Features:

 

1. Rigid casing centralizers can rotate freely and slide up and down on casing, and can be fixed on a certain part of the casing by retaining screws.

 

2. It can scrape mud cakes off and clean borehole wall during running casings, and make cement slurry form bumpy flow and improve the displacement efficiency during cementing, centralize the casing in deflecting well and horizontal well.

 

3. It acts as a sliding bearing when the casing is requested to rotate.

 

Aluminum alloy rigid casing centralizer

 

Main specification: 13-3/8"*17-1/4”, 9-5/8"*12”, 7"*9-1/8”, 7"*8-1/4”, 5-1/2"*7-3/4”,  4-1/2"*5-3/4”

 

1. Generally used in the horizontal well. It has light weight and the good function of centralizing. The contract area between the spiral rigid casing centralizer and the borehole walls is large.

2. It can make cement slurry form bumpy flow to improve displacement efficiency and cementing quality during cementing.
