Aluminium Spiral Vane solid rigid centralizer provide the right feature for getting a good primary cementing job with maximum wellbore standoff with suitable functionality. Straight vane solid rigid centralizers provide ultimate drag and torque reduction with maximum fluid by pass.
Roller Centralizer is a complete mechanical friction-reduction solution designed for extended-reach wells. It reduces torque, drag, casing wear, tool-joint wear and differential sticking while also improving directional control, ROP and hole cleaning. In Low Drag Roller Centralizer, all rollers are arranged in horizontal direction. This kind of arrangement of rollers efficiently reduces dragging force.
Available size is 4-1/2” to 13-5/8”. Any special configuration can be supplied on customer’s demand.
Low Torque Roller Centralizers are specially designed to run in inclined or horizontal section. The rollers envelope outside diameter is kept slightly larger than the centralizer fins envelope outer diameter. The Rollers envelope inside diameter is kept slightly larger than the fins envelope inner diameter. When casing equipped with Roller Centralizer runs into the deviated or horizontal hole, the 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 reduces this impact. Torque reduction is provided by vertical alignment of rollers on the periphery of Roller Centralizer.
Available size is 4-1/2” to 13-5/8”. Any special configuration can be supplied on customer’s demand.
Heavy Duty Welded Spirolizer is designed for high deviated horizontal well where casing centralization is the main consideration. The spirolizer system is made of steel, giving it a toughness advantage over other materials and alloys in different style, but normally straight or curved vane is used. It ensures positive stand-off, maximum flow, maximum well bore stabilization, maximum holding strength, decreased drag. Both spiral and straight fin designs minimize drag forces while running pipe. The fins glide smoothly on the low side of horizontal boreholes. It can be made to float between casing stop collars or be secured to the casing OD, if it is required to rotate the casing while cementing. Due to inclined or spiral fins they help to create turbulence in the fluid which removes any wellbores debris or mud cake deposited and helps in smooth running in of the casing string.
