ZOD- HCS is suitable for well completing task in water sensitivity layer. It has strong adsorption group and cationic group, so it can stably absorb in the surface of clay. It has high cationic density, avoid low cationic density and weak swell preventing, which are the shortcomings of macromolecule polyamine inhibitor. ZOD-HCS can long-lasting prevent clay hydration expansion and particle migration. The concentration of swelling inhibitor has little influence on ZOD-HCS’s adsorption and preventing swell function. ZOD- HCS has strong resistance to liquid scour, also has effective function in reducing and eliminating the damage for petroleum reservoir in well completing task and water flooding task. ZOD- HCS has good compatibility with acid, alkali, salt, surfactant and other additives.
