摘　　要：在前人研究的基础上,建立了3种外边界条件下的三重介质非牛顿流体的渗流模型,并且利用拉普拉斯变换对模型进行了求解;绘制了3种边界条件下的典型渗流曲线,并且利用渗流理论对曲线不同阶段进行了分析。结果不仅可以用于试井解释,而且有助于人们对此类油藏进行更好的认识和评价,为油藏的生产提供科学的依据。Based on the achievements of the predecessors, the well test models of non-Newtonian fluid＇s flow in triple media reservoirs with three kinds of outer boundary were established, which were also solved with the Lap lace transformation. The typical seepage curves of the three models were protracted and the features of different period of the curves were analyzed from the seepage mechanism. The drawn results can be used for well test interpretation, and will help people more deeply understand and more accurately evaluate the reservoir.
