Product Usage

This product can be directly used in various water-based drilling fluid systems, and is often used in conjunction with polyacrylate series treatment agents. It has the characteristics of significant precipitation effect, high thermal stability, small water loss under high pressure, dense and smooth mixed cake, small friction coefficient, strong resistance to salt pollution, good shear dilution performance, etc. It also has properties such as resistance to lime and gypsum. . However, when encountering calcium chloride solution with high concentration, flocculent precipitate will be formed. It is widely used in oil fields, gas fields, metallurgy, geology, coal and other departments as drilling mud treatment agent, deep well anti-temperature drop water loss agent and flocculant. The general dosage is 0.5-1.5%.
