Relative permeability modifier (RPM) is proven to be effective to control water production. In this study, the static adsorption and disproportionate permeability reduction of RPM were investigated. Experimental results indicate that the static adsorption of RPM on quartz sands and reservoir sands, which is in line with Langmuir adsorption isotherm, is affected by electrostatic interactions and wettability of solid surface. Adsorption on reservoir sands is far less than that on quartz sands and RPM can render the oil-wet quartz plate to be weakly water-wet plate. Physical simulation results show that RPM has good disproportionate permeability reduction effect to control water production.
