| 摘 要： | 用真实砂岩微观模型进行微观水驱油试验．研究孔隙结构非均质性对剩余油分布的影响。结果发现．形成微观剩余油分布的模式有：细小孔隙网络结构中的局部死油区、细小孔道中的原油、与流向垂直孔道中的原油段塞、大孔道中的油斑或油膜、盲孔中的原油；影响剩余油微观分布的因素有：储层孔隙网络结构、压力场分布、原油性质、岩石润湿性。

| Abstract: | A model of real microscopic sandstone real is used to conduct a water drive displacement test, study the effect of pore structural heterogeneity on residual oil distribution. The results show that modes of creating microscopic residual oil distribution include dead oil area in minor pore network structures, crude oil in minor pores, crude oil slug in the pores perpendicular to flow direction, oil patches and oil films in the big pore path and crude oil in blind holes, the factors influencing the residual oil micro-distribution include the reservoir pore network structures, distribution of pressure field; crude oil property and rock wettability. |
