Clay stabilizer

The oil layer rock contains a certain amount of clay minerals, which will expand, disperse and migrate in the clear water, and reduce the permeability of the rock. So in the oil field acidification, fracturing or water injection operations, need to add clay stabilizer, inhibit the expansion of clay contains multiple cationic group, will firmly adsorbed on the surface of the negatively charged clay particles, the clay particle surface formed outside the protective film, prevent water wetting and intrusion, which can effectively inhibit the expansion of clay, and can better control the particle transport. This product not only has good swelling prevention and stability ability for clay, but also has washing resistance, long shelf life and good temperature resistance.
