The Method of Interwell Parameter Interpretation for Two-dimensional Water Flooding Simulation

为定量研究二维可视化物理模型注采井间参数,利用计算机像素提取技术建立了二维可视化物理模型饱和度图像的数字化方法,以数字化饱和度场和一维水驱油理论为基础,应用流线模拟技术,建立了二维可视化驱替过程中不同注入孔隙体积倍数时注采井间参数的解释方法。结果表明,利用像素提取技术建立的网格化饱和度场与实际情况相符,利用井间参数解释方法进行模型参数解释方法合理,与实际驱替过程一致。可见该方法对于定量研究二维水驱油试验模型参数以及非均质下水驱油机理的挖掘具有重要理论及指导意义。

In order to quantitatively study the interwell parameter of a two-dimensional visualized physical model,computer pixel extraction technology was used to process saturation image of two-dimensional visualization physical model,based on digitized saturation field and one-dimensional water flooding theory,streamline simulation technique was used to establish an interwell parameter interpretation method for different injection pore volumes in two-dimensional water flooding experiment.The results show that digitized saturation using the pixel extraction technology is in accordance with the actual saturation image,and the interwell parameters explained are reasonable.It provides a guidance for quantitatively studying modeling parameters two-dimensional water flooding and water flooding mechanism under heterogeneity condition.
