摘　　要：采用对比法研究了磁处理对钻井液中粘土胶粒表面电性的变化规律，研究结果表明，磁处理后粘土胶粒表面Ｚｅｔａ电位提高。为进一步解释磁处理使钻井液粘度、切力降低的作用机理提供了理论依据。The change of potential of clay colloidal parti-cles with the magnetic treatment was analyzed by contrast.The study shows that the zeta potential at the surface ofclay colloidal particles goes up after the magnetic treat-ment.A theoretical basis is so applied for studying themechanism of lowering the viscocity and shear force of drillfiuids after magnetic treatment.
