Product Details

API Bonded Composite Centralisers For 13-5/8 inch Casing To Be Run Inside 14.75 inch Open Hole

 

 

Features

 

  • Reducing lower casing resistance phenomenon, making the casing smoothly down to the design position;
  • Making casing centralizer well centered within the well;
  • Reducing the sticking phenomenon so  that can make the annular space hydrostatic pressure balanced;
  • Reduce channeling, improve the mud replacement efficiency, thus improve the cementing quality.

Description

 

The composite centralizer plays the role of centralizing the casing during operation. Made of composite material with low coefficient of friction, heat resistance and high durability. Reliable and functioning even in extreme wellbore conditions, the centralizer can withstand high shock loads and is highly wear resistant.

 

It has a smooth tapered structure and is available with straight and helical blades. Easily passes through obstacles in the wellbore and is suitable for horizontal applications. Enables the casing string to reach total depth efficiently, provides optimal spacing for mud displacement, and greatly enhances cementing operations.
