摘要
以任意形状二维均质油藏的定解问题为基本的数学模型,推导了实空间和拉氏空间中的边界元数值计算方法。以矩形封闭油藏和圆形定压油藏为计算实例,将边界元数值计算结果与解析解结果进行了对比,验证了其精度,并在此基础上计算了含两口井的任意形状二维均质油藏的压力动态特征。
Based on a two-dimension homogeneous mathematical model with arbitrarily shaped boundary, two kinds of BEM either in the Real-domain or the Laplace-domain is presented in detail. The methods are verified against analytical solution for simplified rectangular and round reservoirs, so pressure-transient behaviors characters in two-dimension homogeneous reservoir with arbitrary shape are calculated.
