The product is composed of organic cationic polymer and a variety of additives. It has high efficiency and anti-swelling, wide range, long term and effective, simple usage and good dispersion. Theorganic cationic polymer molecular chain contains multiple cationic groups, which can obviously prevent the hydration expansion and dispersion migration of clay minerals in the reservoir. The product has appropriate molecular weight and can be applied to high permeability and low permeability oil and gas reservoirs. Moreover, its unique rigid structure can enter the clay mineral layers and stabilize the clay under the action of a variety of chemical forces.
