摘　　要：针对圆形封闭复合油藏,提出一种新的用于预测产量的标准曲线图版。沿袭Fetkovich和Carter的思路建立曲线,其原理为一组合适的无量纲绘图变量,理论上只对应唯一一条以边界流动为主的曲线,通过该曲线,可以很容易对油藏流动特征进行分析。该方法具有较强的实际应用价值。A new standard curve chart for projecting production has been proposed in accordance with circular confined complex reservoir. That is to establish curve following the thought of Fetkovich and Carter, which uses a set of dimen-sionless plotting variables. Theoretically, it only corresponds to one curve, which is dominated by boundary flow. Reservoir flow can be analyzed easily with this curve. This method is very practical.
