- With the development of computer science, the numerical simulation of oil reservoirs has been advanced and widely applied. In this paper, according to the surfactant flooding mechanism, a mathematical model for three dimension two-phase three-component surfactant flooding is established. The numerical difference equation is solved using implicit method for pressure and concentration terms and explicit method for saturation terms. A new method is used to treat the relation between the adsorption of the surfactant and the relative permeability curve, which reduces the discrepancy between the mathematical model and the data from actual production. The model is programmed into software using FOR90 language. The software is used to study the surfactant displacement in Chao 61 district of Daqing oilfield. An optimization is done for the injection plan of the surfactant. The oilfield experiment shows that the optimal scheme reduces the threshold pressure of low permeability reservoirs and increases the water absorption rate. The reservoir production ratio increases as well.
