Powdered Defoamers

This powdered defoamer is refined from dimethyl silicone oil, representing a novel, high-efficiency formulation that combines the advantages of polyether and organosilicon compounds. It disperses rapidly and thoroughly in water, maintaining excellent foam suppression and defoaming performance at low concentrations to meet long-term foam control requirements. Suitable for water-based drilling fluids, completion fluids, and workover fluids, it demonstrates superior efficacy in reservoir-specific formulations. This defoamer can be directly added to the system during use, with enhanced performance particularly when surfactants are employed. This defoamer is also suitable for brine systems and plugging slurries, with minimal impact on drilling fluid rheology. It performs effectively in both monovalent and divalent saltwater environments.
