Product Description
Spiral Blade Solid Body Rigid CentralizerSpiral Bladed Solid Body Centralizer /Straight Solid Body Centralizer

Rigid centralizers are an integral part of the cementing process. They provide the mechanism that centers the casing in the hole and allows uniform cement flow around the casing to help protect it at all points. Several styles of centralizers are available for matching different well specifications and hole sizes, including turbulence generating designs that help clean the annulus and distribute the cement more evenly and uniformly. All models offer ample clearance for fluid passage and are extra effective in centering the casing, even in highly deviated holes and improve cement flow by reducing the effects of channeling. 


Casing centralizer is one of the necessary conventional casing accessories, upon well operationscompletion, the rational use of casing centralizer can play the role of:
Reducing lower casing resistance phenomenon, making the casing smoothly down to the design position;
 
Reducing the sticking phenomenon to make the annular space hydrostatic pressure balanced;
 
 
 Spiral Blade Solid Body Rigid Centralizer
Reduce channeling, improve the mud replacement efficiency, thus improve the cementing quality.
 
 
 
 
The reset force of double bow type centralizer is higher than that of single bow centralizer, centering centering performance is better than that of single bow type.
 
Application
 
 
 
Solid rigid casing centralizers are suitable for deviated wells and horizontal wells, to help center the casing in the wellbore, allowing even distribution of the cement around te casing during cementing operations.
 
 
 
 Features for straight blade rigid centralizers:
 
 Spiral Blade Solid Body Rigid Centralizer
 
a. Easy to install.
 
b. Less flow restriction than other centralizers.
 
c. Unaffected by lateral load.
 
d. Casing moves freely within the centralizers.
 
e. Reducing differential sticking and casing contact.
 
 
 
 Features for spiral blade rigid centralizers:
 
a. Reducing gouging and scraping of formation.
 
b. Maximum wall contact.
 
 
c. Spiral blades allow better cement coverage.
