Know All About Rigid Centralizer
2
Rigid Centralizer is one of the most fantastic
machines. It provides mechanism that centers the
casing in the hole and allows uniform cement flow
around the casing to help protect it at all
points. All the models of this centralizer offer
ample clearance for fluid passage and are extra
effective in centering the casing.

How Are Rigid Centralizer Helpful?
4

• The use of off-center rigid centralizers on
  casing maintains a minimum annular space on the
  low side of a deviated well. It improves
  cementing operations in such deviated wells with
  whole enlargement problems.

5

• In inclined well, the drilling tools are
  non-concentrically aligned in the borehole. The
  axis of the drill string appears below the axis
  of the borehole. Thus, in inclined wells changes
  the flow hydrodynamics in the ring space. This
  change is amplified which leads to the
  drilled cuttings move up the well along the
  bottom wall of the hole.

6

• Through carbonates or sloughing formations in
  deviated wells, caverns can cause problems in
  hole cleaning and cementing operations. Since, in
  hole-enlargement areas, the flow of both drilling
  fluid and cement is principally high on the side
  of the well, between the pipe and the top wall of
  the well.

One of the solutions has been the use of Rigid
Centralizer as it ensures minimum standoff of the
casing and the bottom wall. The use of this
centralizer maintains enough annular space
completely around the casing to allow better
fluid flow.
