中文摘要：
为了定量研究岩石细观渗流特性,对岩心薄切片扫描图像进行了分析,并实现了沉积类岩石3个主要形成过程（沉积、压实和成岩作用）数字仿真的二维数字岩心重构,对结果进行了可视化处理.结果表明：在数字岩心构建过程中,参数α控制着石英胶结物沉淀的优先位置,增生指数β控制着胶结物优先增生的几何趋势,κ则控制着孔隙度下降的数量,压实因子λ反映上覆岩层压力,λ越大,孔隙压缩程度越高.
英文摘要：
In order to quantitatively study the meso-scale permeability of rocks,the reconstruction of 2D digital core was performed through analysis of the scan images of rock thin sections and simulation of three main processes（sedimentation,compaction,and diagenesis） involved in the formation of a sedimentary rock.The reconstructed digital core was visualized.The results show that parameter α controls the prior precipitation position of quartz cement,hyperplastic index β controls the geometrical trend of cement priority hyperplasia,and parameter κ controls the porosity decrement.The compaction index λ reflects the overburden pressure.The degree of pore compaction increases with the compaction index λ.
