Product Description 7'' Resin Composite Centralizer Casing with Metal RingsCasing centralizer is one of the necessary conventional casing accessories, upon well operationscompletion, 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. The reset force of double bow type centralizer is higher than that of single bow centralizer, centering centering performance is better than that of single bow type.

Spiral blades increase annular turbulence.2. With the shape of stream-lined, it enables casing run easily in wellbore.3. Both straight blade and spiral blade are available.4. The material can be cast steel or cast aluminum. Centralizers are an integral part of the cementing process. They provide the mechanism that centers the casing in the hole and allows uniform cement flow around the casing to help protect it at all points. Several styles of centralizers are available for matching different well specifications and hole sizes, including turbulence generating designs that help clean the annulus and distribute the cement more evenly and uniformly. All models offer ample clearance for fluid passage and are extra effective in centering the casing, even in highly deviated holes and improve cement flow by reducing the effects of channeling.
