Surfactant/polymer flooding enhances oil recovery by increasing water viscosity and decreasing water/oil interfacial tension. Researches have proved that well pattern has a significant effect on the development performance of surfactant/polymer flooding. Based on reservoir numerical simulation method, the paper studies the development performance of surfactant/polymer flooding using line drive well pattern, five-spot well pattern, nine-spot well pattern, inverse nine-spot and inverse seven-spot well pattern. Results show that the line drive method and five-spot method achieve the highest oil recovery while that of the inverse seven-spot well pattern is the lowest. Mechanism analysis indicates that the displacement efficiency is the dominate factor behind the result. So when determining which well pattern should be used for surfactant/polymer flooding, the displacement efficiency have to be increased as much as possible. Besides, the well pattern should be reasonably designed so that the injection and production wells can be perpendicular with the high permeability channels in order to reduce channelling flow of chemicals. When the heterogeneity of an actual large-scale oilfield is strong and complex, several well patterns may be used together.
