摘　　要：在已有的Fetkovich和Blasingame等生产数据分析方法的基础上,建立了圆形边界均质油藏垂直井径向流下的非达西渗流模型,绘制了Fetkovich与Blasingame非达西流情况下的典型曲线。该连续生产数据分析方法能通过不关井的连续监测生产数据获得常规关井试井分析同样的油藏解释成果数据,解决了低渗透油藏长时间连续监测资料分析应用问题。Based on analysis methods of the existed Fetkovich and Blasingame production data,the non-Darcy flow model of the circular boundary homogeneous reservoirs with vertical wells radial shed is built,and the typical curves of the Fetkovich and Blasingame in case of non-Darcy flow are drawn.This analysis method of the continuous production data through the continuous monitoring production data of unclosing well can get the same interpretation results of reservoir from the well testing analysis of conventional closing well,which solves the applied problems of data analysis for a long time of continuous monitoring in low-permeability reservoir.
