摘　　要：应用井间脉冲测试技术确定了两层无限大均质油藏参数 ,引入两层油藏的地层系数比、导压系数比对两层流量进行匹配 ,从而建立了两层无限大均质油藏井间脉冲试井理论模型 .利用压力叠加原理得到观察井处综合压力的解析解 ,并应用割线法绘制了典型曲线 ,为准确描述层状油藏、解释油藏平面非均质性提供了一种实用方法 .By application of the technology of pulse well testing, this paper determined the parameters of two layer infinity homogeneous reservoir. The ratio of formation coefficients and the ratio of coefficients of pressure derivative were used to match two layer flow rate. Analytic solution to integrated pressure at the observed well was achieved by using the principle of pressure superposition. The type curve of secant method was plotted. A practical method was provided in order to describe accurately layered reservoirs and interpret plane heterogeneous of reservoirs.
