Rigid Centralizers

Both straight blade and spiral blade are available, and designed for use in highly deviated and horizontal well.Spiral blade increase annular turbulence, with its stream-lined shape, it enables casing to run easily in wellbore.

Roller centralizers are mainly used for big high-deviated wells and horizontal wells, for casings being centered. It can make sliding friction into rolling friction between casings and borehole wall, and can effectively reduce the friction under running casing. In addition, levorotatory spiral groove has cleaning effect, and can change state of casing blocked in the process of construction, so that ensure casing running is smooth. Roller centralizer can also remove wellbore cake, and improve mud replace efficiency etc. Roller centralizer is an indispensable cementing accessory tool in the completion of big high-deviated wells and horizontal wells.
