【Abstract】 With systematically summarizing modeling experiment result of oil driving water and water driving oil under various conditions, microscopic seepage flow characteristic of reservoirs is analyzed in detail. Forming mechanism of irreducible water and residual oil is expounded. Six microscopic distribution types of remaining oil are described, including oilbearing in intermedian grain pore, matrix solution void, grain solution void, fracture, impurity micropore and grain micropore. Three distribution patterns including distribution pattern of midlarge pore, midgreat throat continuous saturated oil, smallmid pore, middle throat local continuous saturated oil and slender throat intermittent oil cutting and its distribution rule in different oilbearing periods are described too.更多还原
