API Nylon Composite Polymer Centralizer
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.
Charactors:
Available in 3 ½" to 20" sizes. Customized sizes are also available.
Application: Developed specially for horizontal and extended reach wells.
Low coefficient of friction centralizer made from a thermoset polymer.
Up to 50% lower coefficient of friction over steel centralizers.
Increased length compared to common types of centralizers with no blade overlap to prevent bulldozing cuttings.
Available in right or straight vane orientation.
These Thermoplastic Centralizers withstand high well bore temperatures of up to 230 degrees Celsius.
