Bonded Composite Centralizer For Casing Inside 14.75 Inch Open Hole
API Bonded Composite Centralisers For 13-5/8 inch Casing To Be Run Inside 14.75 inch Open Hole
The composite nylon centralizer is used during running and cementing operations to centralize casing. Made of advanced composite, the one-piece centralizer has a low coefficient of friction, this centralizer withstands high-impact loading and is highly wear resistant.
Features
- 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;
- Making casing centralizer centered within the well;
- Reduce channeling, improve the mud replacement efficiency, thus improve the cementing quality.
Description
The composite centralizer is used during running and cementing operations to centralize casing. Made of advanced composite, with low coefficient of friction, heat resistant, and highly durable. Performs reliably even in extreme wellbore conditions,this centralizer withstands high-impact loading and is highly wear resistant.
It has a smooth, tapered construction to easily pass obstructions in the wellbore, suited for horizontal applications. Enables casing strings to reach total depth efficiently, provides optimal standoff for mud displacement, and greatly enhances cementing operations. Available in straight and spiralblade configurations.
