摘　　要：利用小型预压裂测试资料,以Mayerhofer思想为基础,运用物质平衡及Duhamel叠加原 理,进一步完善典型参数的确定方法,确定了一种求取地层渗透率简单易行的方法,并通过实例对 模型的适应性进行了论证,该方法对于矿场具有重要的现实意义。By use of testing data for microfrac well and according to Mayerholfer's thought, this paper provides a sample methodology, which is based on the material balance and Duhamel superposition principle, to determine the permeability of reservoir, and its truth is verified by the practical case of fracturing well. The approach is considerably important for the analysis of pressure decline in the fracturing well in practice.
