摘　　要：运用岩石薄片、铸体薄片、物性、扫描电镜和压汞等资料,对老新油田新沟嘴组的储层特征和微观结构进行了综合研究,认识到储层孔喉分布和孔隙结构的非均质性是影响水驱油效率的主要因素。This paper had conducted a comprehensive research on the features and microstructures of Xingouzui Formation reservoirs in Laoxin Oil Field by studying the properties of rock slices and casting body sections with scanning electron microscope and mercury penetration method. It turned out that water flooding efficiency is mainly affected by pore throat distribution and the anisotropy of pore structure.
