Title: Rigid Centralizer Working Process


1
Rigid Centralizer Working Process
2
The Rigid Casing Centralizer is basically a
mechanical device which is secured around the
casing at various locations.
3
Features of Rigid Centralizer
  • It has hollow steel blades with a rounded smooth
    profile.
  • It can be used in wells where casing
    reciprocation and/or rotation is required.

4
Features of Rigid Centralizer
  • The all-steel design can withstand severe
    wellbore conditions.
  • This is available with or without set screws.

5
How It Works
The centralizer is kept away from making further
contact with the wall as the device continuous
annular clearance around the casing it allows
cement to completely seal around the casing to
the borehole wall.
6
The eccentric structure of the tool is introduced
and the working principle of adjusting the
centralizing azimuth by the automatic rotation of
two kinds directions.
7
The better way to perform is a standoff analysis
for each casing before a cementing job.  Also,
the exact number of Rigid Centralizer required
and their placements on the casing are important
to make it work properly. 
8
The lab and field experiments show that the tool
can effectively improve the centralizing degree
of the casing in horizontal wells.
