摘要
Based on the characteristics of surfactant flooding, a mathematical model for surfactant flooding was established. The changes in adsorption-retention, convection, diffusion of surfactant, and influence of concentration upon the relative permeability curve are included. The novel description of the adsorption quantity of surfactant and the relative permeability curve are presented. The model was applied to surfactant flooding in a surfactant flooding pilot test at Daqing, and the influences of surfactant concentration, amount of injection, and slug combination mode on development effect and economic benefit are quantitatively analyzed, and the injection plan is optimized. After the implementation of surfactant plans in the oilfield, we obtained the desired results.
