摘　　要：油藏几何形状特别是油藏边界对井底压力动态响应有显著的影响。对于复杂边界问题 ,常规的解析法则显得无能为力。这就需要用数值方法求解 ,边界元法具有降维、计算速度快、精度高以及求解油藏内点方便等特点。本文根据边界元理论推导了油藏井底压力响应的计算方法 ,并将其计算结果与常规解析方法求解结果相比较。Reservoir geometry especially such as reservoir boundary significantly influences dynamic response in underground flow.The conventional analytical methods are limited to simple and regular geometries.To the complex reservoir geometries,only that of The Boundary Element Method (BEM),which has the characteristics of reducing dimension,calculating fast,high precision and giving the inter solution easy,is needed.The paper obtained the calculation method to solve unsteady state flow problem and compared the results with the ones that resulted from the conventional analytical method.
