摘　　要：水驱是提高原油采收率的重要方法,我国除四川以外,19个采油区块均采用注水方式开采。由于油藏多孔介质油水多相流动的复杂性,理论和试验研究都存在一定的局限。本文参考油气井工程研究所拍摄的实例照片建立物理模型,经过合理的简化建立数学模型,借助fluent模拟软件进行模拟。模拟结果表明,岩石的润湿性和油、水的界面张力是影响油、水两相流动的重要参数。Water flooding is an important method of raising oil recovery. In China, 19 oil-production blocks take the way of water injection in the exploitation except for Sichuan Province. Because of the complexity of oil-water multiphase flow in porous media of the reservoir, there are some limitations for theoretical and experimental studies. Referring to a photo pictured in a oil and gas wells engineering institute, a physical model was established. After reasonable simplification, a mathematical model is set up. Then, simulation processed by using simulation software Fluent. Simulation results show that the wettability of the rock and oil-water interracial tension are important parameters affecting oil and water two-phase flow.
