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。 Waterflooding is an important method to improve oil recovery. In addition to Sichuan, all 19 oil recovery zones in China are mined by waterflooding. Due to the complexity of oil-water multi-phase flow in porous media, there are some limitations in theoretical and experimental studies. In this paper, the photos taken by the Institute of Oil and Gas Engineering Photographs to establish a physical model, after a reasonable simplification to establish a mathematical model, using fluent simulation software simulation. The simulation results show that the wettability of the rock and the interfacial tension of oil and water are important parameters that affect the flow of oil and water.
