摘　　要：通过对文东油田沙三中亚段岩芯观测、岩石薄片、铸体薄片、扫描电镜以及压汞资料分析储层微观孔隙结构特征的基础上,通过不同渗透率的真实储层模型水驱油实验,分析了储层微观孔隙结构与驱油效率的关系,及其对微观剩余油分布模式的影响,进一步研究了低渗透储层的微观水驱油机理。On the basic of the feature of microscopic pore structure in reservoir rock of ES3 in Wendong oil field according to the data of core observation, rock slice,electron microscopecanning, Hg testing and based on experiment of water-drive-oil model in actual reservoir rock by using mutativepermeability, this paper analyses relationship between microscopic pore structure and efficiency of displacement,and the influenceto microcosmicremaining oil distribution model. Furthermorethe author researches microcosmicdrive-oil mechanismin low permeability reservoir rock.
