Product Synthesis and Process: This product is a drilling fluid filtrate reducer synthesized through polymerization and sulfonation using phenol as the main raw material. It exhibits strong resistance to high temperature, salt, and contamination, demonstrating excellent filtration control even in saturated salt water at high temperatures up to 180°C. Additionally, it reduces friction and drilling fluid viscosity;

Applications: This product has good compatibility with various additives and is suitable for multiple water-based drilling fluids, especially for deep well drilling fluids in complex formations, saturated salt water drilling fluids, and directional well drilling fluids. It is applicable in drilling fluids with salt content up to 15% and can be used in high-concentration salt environments up to saturated salt water drilling fluids.
