摘要： 为有效解决凝灰质储层渗透率精细解释的问题，以南贝尔油田为例，利用取心井岩心分析孔隙度、渗透率资料，利用流动单元指数FZI值进行流动单元划分，并建立了各类流动单元的渗透率精细解释模型。将优选反映储层变化的测井变量及运用判别分析法建立流动单元的判别方程应用于非取心井段。结果表明，分流动单元计算的渗透率其模型解释精度明显提高，为凝灰质储层渗透率解释提供了一种新的有效方法。

Abstract: In order to solve the problem of fine interpretation of permeability of tuffaceous reservoir,taking the Nanbeier Oilfield as an example，this study uses the porosity and permeability data from coring wells to evaluate the FZI and divided flow units by FZI, then establishes a detailed permeability interpretation model for each type of flow unit. It optimizes the logging variables so as so reflect reservoir changes and applies discriminant analysis method to establish discriminant equation of flow unit for non-coring intervals. The results show that the interpretation accuracy of permeability model calculated by shunt flow unit is obviously improved, which provides a new and effective method for permeability interpretation of tuffaceous reservoir.
Key words: log interpretation    tuffaceous reservoir    flow unit    permeability    Nanbeier oilfield
