■ wide application range
■ Inhibit clay expansion effectively
The product can effectively adsorb on the surface of clay, prevent the expansion and migration of water-sensitive minerals, reduce the damage of water-based fracturing fluid to oil and gas reservoirs, and resist the erosion of acid, salt, alkali and oil-water. It is long-term effective and suitable for fracturing fluid, active water, perforating fluid and other working fluids.
