Product Description
Clay stable agent ST-SHYL133 is a kind of multicomponent compound composed mainly by organic polymers, It can prevent the swell of clay after absorbing water, control the permeability of the formation, avoid the pollution of the formation. The principle of this product is the cation on the branch of the macro-polymer attached between the clay and the mineral particles, compress the double electrical layers, reduce the hydration repulsive forces, control the swell of the clay and the movement of the particles.
