可动凝胶调驱是一种正在快速发展的提高石油采收率的新技术,由于对其渗流力学行为特征缺乏深入的研究,不能较好地描述其渗流规律,现场应用缺乏足够的理论指导。在可动凝胶流变特性实验、可动凝胶在多孔介质的渗流特性实验的基础上,通过对质量传输流体力学、化学动力学的深入研究,初步建立了可动凝胶体系驱油渗流数学模型方程组,较好地描述了可动凝胶体系在多孔介质的复杂渗流行为,为进一步研究可动凝胶体系渗流理论和现场实践打下基础。

The movable gel as profile control is a new EOR method with brilliant prospect. As there was no thorough research on its seepage characteristic, the field application of movable gel was lack of theoretical guidance. Based on the rheological behavior experiments of movable gel and its seepage characteristic experiments in porous medium, the seepage model of movable gel was established in according to indepth research on mass transportation fluid mechanics and chemical kinetics. The seepage model could represent the complex seepage behavior of movable gel in porous medium, which laid the foundation for the seepage theory and field application of movable gel.
