Casing centralizer
Product overview:
Casing centralizer is one of the necessary conventional casing accessories, upon well operationscompletion, the rational use of casing centralizercan play the role of:
Reducing lower casing resistance phenomenon,makingthe casing smoothly downto the design position;Making casing centralizer centered within the well|;Reducingthe sticking phenomenonto make the annular space hydrostatic pressure balanced;Reduce channeling, improve the mud replacement efficiency, thus improve the cementing quality.The reset forceof double bowtype centralizeris higher than that of single bowcentralizer, centering centering performance is better than that of single bowtype.
Instructions and notices:Welding type centralizercover on the casing from male threadedend, according to the lengthuniformlydistributed.springtype centralizer adoptspin connection, the methodof entering to the wellis the same as above.
When casing centralizer slidesinto the well eye, thespeed must be slowly and evenly.
