摘　　要：鄂尔多斯盆地纳岭沟铀矿床局部隔水层主要有2类,即沉积作用形成的泥粉质局部隔水层和成岩作用形成的钙质局部隔水层。为了达到局部隔水层的最佳识别效果,采用多曲线加权视电阻率曲线重构技术进行岩心标定。综合研究局部隔水层及矿体的发育规律,以局部隔水层及矿体的空间特征作为约束条件,建立局部隔水层与矿体三维可视化模型。There are two genetic types of partially impermeable layer in Nalingou uranium deposit of Ordos basin： mud -silty type partial impermeable layer by sedimentation and calcareous type partial impermeable layer by alia- genesis. This thesis adopted multi - curve apparent resistivity curve reconstruction and core calibrated to achieve the best results of identifying partial impermeable layer. Based on research of the distribution of partial impermeable layer and ore - bodies, regarding the characteristics of partial local impermeable layer and the ore body, we estab- lished a partial local impermeable layer and ore - bodies three - dimensional model with the help of advanced 3 D modeling software.
