Abstract: 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.
