Description of centralizer:
Casing Pipe Centralizer cementing tools, it makes simple, and beautiful structure, durable, strong centering
force, prone to overcome the original welded lifter desoldering , is a kind of centralizer can
ensure quality of drilling cementing. The sort is various, according to the structure can be divided
into the roller type, the sliding block type, automatic reversing type, etc. Different structure and
material of centralizer, applies to different types of eccentric wear oil well. On the part of eccentric
wear prevention, the most critical is installation location, spacing, and number.
Product's advantage of rigid body casing centralizer
Application:in deviated and horizontal wells, liner overlaps, and shoe joints.
Suitable for either cased or open hole.
Vane ends are beveled 30 degrees relative to casing centralizer to provide excellent lead into restrictions, and reduced drag when running into hole.
Wide vanes distribute load from the casing string into the well bore without gouging.
The design of the vanes keeps running forces at a minimum.
