A device fitted with a hinged collar and bowsprings to keep the casing or liner in the center of the wellbore to help ensure efficient placement of a cement sheath around the casing string.
It is being lowered into the hole after drilling has reached total depth and the drill string withdrawn. This allows the casing string to be cemented to the borehole without any 'thin' cement areas.

Eneroil developed the Solid Body Low Drag Roller Centralizer as axial drag friction reduction tool. The contact area of the rollers with the casing or borehole wall functions well in under pressured conditions, where the risk of differential sticking is high.
The Low Drag centralizer with steel rollers helps to avoid ploughing through wellbore material that has settled, alleviating major drag problems in deviated and horizontal wells.
Solid Body Low Torque Roller Centralizers are specifically built to run in an inclined or horizontal section. The rollers outside diameter are kept slightly larger than the centralizer blades outer diameter.
When casing equipped with Solid Body Low Torque Roller Centralizer runs into the deviated or horizontal hole, sliding friction between the casing and the borehole is converted into rolling friction. In case of irregular hole diameter, the borehole wall has an impact force on the spiral centralizer during running casings, the use of rollers reduce this impact.
The console achieves remote control and power regulation of solid-state H.F. welder,installed with LCD;also it has indicators of armature voltage,field voltage on DC speed regulation cabinet and indicators of DC voltage,DC current on welder.Installation of power-speed closed loop control function is optional.The console has design difference according to different types and quantities of matching DC speed regulation cabinet.

Specification:
1.The impact resistance of ceramal wear-resisting layer higher than middle 16mn steel plate, no crack, no falling off.
2.The average hardness is hrc60-70 in the ceramal wear-resisting layer, more than 3 times that of middle plate.
3.The friction factor in the ceramal wear-resisting layer is lower than middle plate by 50%.
4.The corrosion resistance from acids, alkali and salt in the ceramal wear-resisting layer is more than 10 times that of 16mn steel plate.
5.The ceramal wear-resisting layer is laid out reasonably in calculation by the operating mode of the scraper, making the resistance and noise reduce at lowest.
6.After the cladding treatment, the middle groove increases in intensity wholly, not easy to become deformed after the stress.
Description:
Casing Centralizer is a device used to place the casing at the center of the hole so as to improve the efficiency of the cementing. It is an important device because if the Casing Centralizer touches the formation at any part of the hole, then cement slurry does not pass through the area of the contact resulting in a poor cementing job.

Rigid casing centralizer
As one useful cement tool, rigid centralizer enables casing run easily in wellbore with its shape of stream-lined. There are two kinds of rigid centralizer available: spiral blade rigid centralizer and straight blade centralizer.
The material for both kinds of centralizers can be cast steel or cast aluminum.
Eneroil's spiral vane thermoplastic centralizers are manufactured using engineered material and are designed for the maximum durability, drag, and friction downhole achievable in a centralizer. Additionally, these centralizers have lower friction factors, a rotational torque reduction, and increased abrasion resistance for a maximum stand-off. Spiral vanes help enhance hole-cleaning by using a maximised flow-by area. The vanes overlap the entire 360° open-hole circumference, which creates a vortex motion to increase fluid velocity with direction. Even without rotation, the vanes are able to induce turbulent flows for an improved cutting and filter cake removal.
Eneroils thermoplastic centralizers are a one-piece construction of superior-quality polymer, with optimum tensile and yield strengths, and are able to withstand high well-bore temperatures while providing a maximum horizontal stand- off.
Eneroil offshore has developed its Single piece Bow Centralizer (S12) model to perform satisfactorily in Open hole as well as Cased hole. These are high quality product, developed to meet and exceed API10 D specifications for use in highly demanding downhole conditions.
Eneroil's Single piece Glider Centralizer (S12) combines the highest restoring force with zero starting force and zero running force. Single piece centralizer is used to position the casing in the center of the wellbore in vertical deviated and horizontal wells, reduce the effect of channeling by reducing pipe movement before Cement sets in and improving the cement flow, this results in more uniform cement thickness in the well bore. S12 centralizers are one piece construction in special high strength Steel which imparts excellent hardness and spring action ensuring an unmatched ability to come back to its original shape after undergoing rigorous stress loads conditions.
