摘　　要：岩石物理的研究对象是由形状极其复杂的孔隙、岩石骨架及多相填充物组成的体系。而在传统的模拟油气藏条件下的岩心试验中,岩心的微观孔隙结构是不可被直接观察和控制的。用图像处理技术对从现场得到的二维铸体薄片进行处理,进而由二维岩心结构重构三维数字岩心。这种数字岩心能最大程度地与实际的岩石接近,能反映地层的一些真实的信息。这对岩石物理的研究有着十分重要的意义。Petrophysical research object was a system consisting of complex pore geometry, rock matrix and multi-phase filling. But the traditional core experiment was on the condition of simulating oil/gas reservoir. In this case the micro-pore structure was not be observed and controlled directly. 2D epoxy-saturated thin section, which was obtained from field cores, was processed by image processing technique, and then 3D digital core was reconstructed from the 2D thin section. This digital core resembles real rock. It can show some true information of the formation. It is a great significance of petrophysics study.
