Achieving a high-quality cement bond requires the complete removal of drilling fluids and filter cakes. Our Oilwell Cementing Spacers are advanced chemical systems designed to separate incompatible fluids while effectively cleaning the casing and wellbore.
By managing the rheological hierarchy during displacement, our spacers—available in both powder and liquid forms—ensure that the cement slurry displaces the mud without "channeling," leading to superior zonal isolation and long-term well integrity.
Rheological Compatibility: Engineered to prevent the formation of high-viscosity "gels" when in contact with drilling mud or cement.
Superior Suspension: High-performance polymers ensure that weighting agents (like Barite or Ilmenite) remain in suspension, even at high temperatures up to 180°C.
Water-Wetting Action: Contains specialized surfactants that convert oil-wet surfaces to water-wet, significantly improving the bond between the cement and the formation.
Customizable Density: Can be formulated for a wide range of densities ($1.05 \, g/cm^3$ to $2.20 \, g/cm^3$) to maintain wellbore pressure balance.
Mixing: Easily dispersible in fresh water or brine. Optimized for rapid hydration in batch mixers or on-the-fly systems.
Volume Calculation: Recommended spacer volume is typically based on achieving a specific annular contact time or a desired displacement height.
Compatibility Testing: We recommend performing "Mud-Spacer-Cement" compatibility tests to ensure optimal performance with your specific field fluids.
Our spacer technology is focused on Total Displacement Efficiency. By combining mechanical scouring and chemical cleaning, our products minimize the risk of contaminated cement, which is the leading cause of remedial "squeeze" cementing jobs.
Established in 2006, Tianjin Kelioil Engineering Material and Technology Co., Ltd. is a high-tech enterprise specializing in the independent R&D and large-scale production of oilfield cementing additives.
