Characteristics of pore structure have an important influence on the water flooding development. In order to improve the recovery rate, it is important to have a research on the relationship between pore structure and oil displacement efficiency. The permeability of the artificial cores in this experiment is 189×10-3μm2, 741×10-3μm2and 21417×10-3μm2. We used the CT technology method to scan the pore structure of the three cores, and did oil displacement experiment to research the effect of pore structure on the oil displacement efficiency. The result shows that the pore and throat common affect oil displacement efficiency: the bigger pore and throat radius is, the better effect of water flooding and polymer flooding is; the smaller pore and throat radius is, the worse effect of water flooding and polymer flooding is. The experiment has studied the influence of pore structure on oil displacement efficiency deep into microcosmic without damaging the core skeleton, improved the basis of oil recovery from the micro and the mechanism.
