Filtration control agent for drilling fluid. CS-VIF
Product Features and Applications
CS-VIF is a high-temperature resistant filtration control agent for drilling fluids, which is a chemically modified crosslinked polysaccharide derived from natural high molecular weight polymers. It has strong shear-thinning properties and can effectively adjust the rheological properties of drilling fluid systems, significantly increasing the low-shear rate viscosity of drilling fluids, improving the dynamic yield point and dynamic shear force of drilling fluid systems, and enhancing the suspension and carrying capacity of drilling fluids. It is suitable for various water-based drilling fluid systems and is easy to use. The product is environmentally friendly and non-toxic.
Product Advantages
Temperature resistance up to 140℃.
Good resistance to salt and calcium/magnesium, can withstand saturated saltwater.
Improves the dynamic yield point of drilling fluids, helping to achieve "low viscosity, high shear" rheological properties of drilling fluids, ensuring good suspension and carrying capacity.
Excellent filtration control performance, able to adjust the mud cake quality.
Environmentally friendly and non-toxic.
