1. Composite centralizer is widely used in horizontal well.
2. Features
1,There is metal collar inside the centralizer,the neck collar material can be aluminium or steel.
2,Sprial or straight can increase strength and annular flow
3,Stream-line can help casing run easily in wellbore or outside casing.
Rigid 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.
solid centralizers have proven to be the casing centralizer which eliminates secondary cement squeezing and assures zonal isolation. The solid straight blade design promotes self-cleaning in the wellbore with less fluid restrictions and drag than bow centralizers and allows pipe to rotate and reciprocate freely inside the centralizer. Solid Centralizers are the superior casing accessories, delivering 360º total cement coverage.
solid centralizers are available for casing sizes ranging from 4 ½” to 20”.
