AC-SI01 is a new type of chlorine free small cationic shale inhibitor with high cationic charge density, which can be effectively adsorbed on the surface of clay particles to prevent hydration expansion of water sensitive minerals and damage to oil and gas reservoirs caused by dispersion migration. The positive ions in AC-SI01 undergo cation exchange with low valent cations on the clay surface. After cation exchange, the polymer is firmly adsorbed on the surface of clay particles through van der Waals forces between ions, forming a protective film that inhibits clay dispersion and migration. The polar end of the cation has a large steric hindrance, which can penetrate into the diffusion double layer and generate electrostatic adsorption with the hydration negative layer of clay particles, forming an adsorption double layer. The synergistic effect with other additives can also prevent the migration of particles and reduce the sensitivity of the reservoir.
