Product Introduction

This product is composed of organic cationic polymers and various additives, with high efficiency in preventing swelling, wide range, long-lasting effectiveness, simple usage, and good dispersibility. Mainly used for clay anti swelling in water sensitive formations, this product can effectively protect the permeability of formations with high mud content from various fluid damage after treatment. The organic cationic polymer molecular chain contains multiple cationic groups, which can strongly adsorb on the exchange points of clay in a network form. Through intermolecular forces and hydrogen bonding, it can adsorb on the surface of clay and significantly prevent the hydration expansion and dispersion of clay minerals in the reservoir. The product has an appropriate molecular weight and can be applied to high and low-permeability oil and gas reservoirs; Moreover, its unique rigid structure can enter the interlayer of clay minerals and stabilize the clay under various chemical forces.
