摘要： 目前,新型可动微凝胶深度调驱已成为老油田大幅度提高石油采收率的重要技术之一。通过室内驱替实验,研究了新型可动微凝胶（SMG）体系在多孔介质中的渗流机理,并建立渗流模型,给出方程解析解;定义有效渗滤系数为新型可动微凝胶体系的表征量,并对模型参数进行系统分析。研究结果对分析计算SMG 溶液在多孔介质中的注入浓度分布、注入压力变化,明确体系作用有效范围等,具有一定的方法参考和理论借鉴价值。

Abstract: At present, new soft movable micro-gel (SMG) depth profile control has become one of the important EOR techniques for old oilfields. By lab displacement experiment, the percolation mechanism of SMG system in porous medium is studied, the percolation model is developed, the equation analytical solution is given. The effective filtrating factor is defined as characterizing factor of SMG system. The model's parameters are analyzed systematically. The research shows that the results could have methodological and theoretical reference values on the analysis and calculation of injection concentration distribution and injection pressure variation and the determination of effective range of SMG solution in porous medium.

Key words: new soft movable micro-gel (SMG), depth profile control, percolation behavior, filtrating factor
