4-1/2" * 6-1/2" Centralizer Downhole Drilling
Product overview:
Casing centralizer is one of the necessary conventional casing accessories, upon well operations completion, 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.
Spring API Centralizer
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. The woven centralizer is connected by pin when in use, the unfolded centralizer can be stacked flatly for convenient storage and transportation.
Rigid API Centralizer
Rigid Centralizers are available in Straight Blade or Spiral models and are made to run on the casing OD to centralize the casing that will be cemented in the wellbore and will also improve cement bonding onto the casing. They are designed to reduce the amount of friction between the casing and the hole, allowing the casing to be inserted more easily into the wellbore; and help prevent the casing string from becoming differentially stuck.
Composite API Centralizer:
The composite centralizer is used during running and cementing operations to centralize casing. Made of advanced composite, the one-piece centralizer has a low coefficient of friction, is heat resistant, and is highly durable. The composite material performs reliably even in extreme wellbore conditions. Unlike many plastic centralizers, this centralizer withstands high-impact loading and is highly wear resistant.
