The study on displacing oil is a new kind of experimental technology based on the macro waterflood displacement experiments, combined with the technology of nuclear magnetic resonance (NMR), mercury injection, etc, to study two phase percolation mechanism to simulate hydrogen oil as medium. According to the displacement fluid T2 cutoff value and infiltration absorption ,displacement function can be divided into displacement mechanism and seepage mechanism of absorption, and quantitative calculate recovery degree of different phase, so as to realize the combination on oil displacement effect of macro and micro pore space.
