This additive is effective below a temperature of 120 degrees Celsius (248 degrees Fahrenheit).
It has a remarkable thickening effect and high viscosity at low concentrations. It effectively suspends weighing agents, insoluble solids, and oil droplets.
It exhibits good synergy with other thickening agents.
It has a strong thickening effect, suspension ability, and stability. It is easy to dissolve and apply in water.
Before use, it is important to conduct a compatibility test.
It has a thickening effect on cement slurry under certain conditions, so it is necessary to apply an appropriate amount of chemical inert spacing agents to separate it from the cement slurry. Fresh water or mixing water can be used as a chemical inert spacing agent.
The professional solution for clean wellbore displacement and slurry integrity.
Product Overview
CS210S is a premium powder-based spacer additive designed to effectively remove drilling fluids and create a clean interface for cement slurry. By providing a high-viscosity barrier, it prevents the detrimental blending of mud and cement, ensuring a high-quality bond and long-term well integrity.
Performance Highlights
Superior Cleaning: Effectively flushes drilling mud from the annulus to prevent contamination.
High Yield at Low Dosage: Achieve a viscosity of ≥5000 mPa·s with a recommended dosage of only 2.0% (BWOW).
Thermal Stability: Maintains performance in temperatures up to 120℃ (248℉ BHCT).
Advanced Suspension: Exceptional ability to keep weighing agents, insoluble solids, and oil droplets in suspension.
Synergistic Compatibility: Can be seamlessly integrated with other thickening agents for customized fluid designs.
