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; Making casing centralizer centered within the
well; Reducing the sticking phenomenon to make the annular space
hydrostatic pressure balanced; 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.
1.These Centralizers are designed for High Restoring Force and Low
Starting Force for centralizing the casing pipe in a Vertical,
Horizontal and Deviated well
2.Premium quality Bows are made of special alloy steel and hot
formed in totally controlled heat treatment plant to achieve the
uniform hardness all over
3.Spec and performance index of bow spring casing centralizer meet
API Spec 10D. The woven centralizer is connected by pin when in
use, the unfolded centralizer can be stacked flatly for convenient
storage and transportation.
Rigid roller centralizer
Rigid casing centralizer is used in deviated wells and horizontal
wells. There are several blades on the rigid roller centralizerthat
can keep casing from contacting the wellbore wall
Roller rigid centralizer
which is most suitable for highly deviated wells and horizontal
wells has two or three rollers in each blade. It can change
slipping friction to rolling friction, so the Roller rigid
centralizer greatly reduces the friction between casing and
wellbore wall and let casing go to desired position smoothly.
Cast aluminum centralizer:
The smooth spiral 360 overlap solid vane design of centralizers
provide max wall contact will not damage wellhead equipment, has
high impact and shock resistance comand fluid swirl. The 30slope
from the body to the height of the vane will eliminate scraping, or
digging into the formation.
The solid cast aluminum centralizers bine with high tensile and
