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 . The parameters of two infinite reservoirs are determined by using the crosswell pulse test technique. The stratum coefficient ratio and pressure coefficient ratio of the two reservoirs are used to match the two flow rates, so that a two-layer infinite homogeneous reservoir is established Crosswell pulse well test theory model.Using the pressure superposition principle to get the analytical solution of observation well comprehensive pressure, and the typical curve is drawn by the secant method, which provides the accurate description of the layered reservoir and the interpretation of the reservoir heterogeneity A practical method.
