Lignite Resin
Catalog NO.: AIMRSE-CHM-ADD-059 Manufacturer PN: CHM-RES-LIG
• Temperature resistance greater than 220°C; no viscosity increase; easily soluble in alkaline environments; strengthens wellbore.
High-temperature, high-pressure loss control agent suitable for all types of water-based drilling fluids. Commonly used in high-temperature wells, with superior temperature resistance compared to conventional polymers.
This lignite resin is compatible with all water-based drilling fluids, primarily functioning to reduce fluid loss while maintaining excellent rheological properties. It exhibits salt tolerance up to 70,000 ppm and calcium resistance up to 3,000 ppm. It requires use in alkaline environments with pH greater than 10 to ensure complete dissolution. This product does not increase viscosity but demonstrates significant resistance to high-temperature, high-pressure fluid loss. Additionally, it stabilizes wellbore walls and reduces scouring.
