基于多重介质渗流的概念模型和数学模型,建立了缝洞型油藏油水两相流三重介质数值试井模型;对模型进行数值求解,得到三重介质油藏两相流试井响应曲线并分析其特征。指出三重介质油水两相条件下的压恢曲线与单相时的不重合,并随着初始油水饱和度的变化而变化,不能直接用单相试井模型来解释两相流试井曲线;提出了先拟合油水产量曲线,再拟合压力恢复曲线的试井解释方法。 Based on the conceptual model and mathematical model of multi-medium seepage flow, a triple-well numerical model for oil-water two-phase flow in fractured-cavity reservoirs was established. The model was solved numerically and the well response curve of two-phase flow in triple-media reservoir was obtained and analyzed feature. It is pointed out that the pressure-recovery curve under the condition of the triple-medium oil-water two-phase does not coincide with that of the single-phase and changes with the initial oil-water saturation. Therefore, the single-phase well test model can not be used to explain the two- In order to fit the oil and water production curve first, and then fit the pressure recovery curve well test interpretation method.
