| 摘 要： | 油藏压力动态分析的常规解析方法大多是建立在规则几何形状基础上,然而实际碳酸盐岩油藏往往是非规则的，伴随着尺度不一的裂缝和孔洞型结构，纯解析方法就显得无能为力。边界元方法是一种边界型数值方法，它把控制微分方程变换成边界上的积分方程，采用Laplace变换，在单相均质微可压缩流体流动的数学模型基础上建立了求解串珠状油藏压力的边界元方法和计算过程；结合该方法计算出的曲线图版，分析了多种不同缝洞组合方式下的压力动态，为求取油气藏特性参数和产能评价提供了技术支持，为试井分析提供了更灵活的理论方法。

| Abstract: | Most conventional analytical methods used in reservoir pressure behavior analysis are based on regular geometry reservoirs.But the actual carbonate rock reservoirs are almost irregular with different size fractures and vug，which makes pure analytical method helpless.Boundary element method (BEM) is a boundary type numerical method，it changes governing differential equations to integral equations of boundaries.In this paper，BEM is established on the basis of single phase，homogeneous and compressible fluid flowing mathematical model by Laplace alteration.Several pressure behaviors are analyzed with different fractures and vug array mode by associating with curve charts worked out with this method.It offers technical support for resolving reservoir parameters，deliverability evaluation and more flexible theory method for well test analysis. |
