The casing centralizer is used to centralize the casing in the borehole to ensure the even solidification of cement
slurry within the annular,which can improve the cement job quality.
Proper selection of casing centralizer is very important for running the casing to bottom hole in horizontal and extended reach well, and it can improve cementing quality by centralizing the casing in hole.
The casing centralizer has non-welded single bow spring centralizer, double-bow spring centralizer, rigid casing centralizer.
The rigid casing centralizer has spiral blade rigid centralizer and straight blade centralizer two kinds. The material of rigid
casing centralizer can be cast steel or cast aluminum.
Characteristics of Casing Pipe Centralizer
1. Super-strength spring steel
2. Model processing, no rivet, no welding
3. 3-section structure for easy transport
4. Starting and resetting force conforms to API standard
