In order to carry out the research and application of the synergy effect of the micro-nano dispersion system (MDS)/polymer combination system,this paper carried out the physical and chemical properties of the MDS/polymer combination system through the interdisciplinary and innovative research methods, taking reservoir engineering, physical chemistry and biological fluid mechanics as the theoretical guidance. By the simulation macro physical simulation, the reservoir adaptability, transmission and migration ability, and the synergisticdisplacement effect are further explored. The results show thatMDS has good hydration expansion performance in polymer solution......
