摘要
本文应用 Ｇｒｅｅｎ 函数方法和 Ｎｅｗ ｍ ａｎ 乘积方法给出了单孔隙介质油藏的源函数表达形式的压力通解，为方便计算给出了两种形式的源函数表达式。借助于褶积积分公式提出了在 Ｌａｐｌａｃｅ 空间内考虑井筒储存效应和污染效应存在时井底压力的计算方法。
General solutions for the seepage flow in single porous medium in vertical and horizontal well are presented by Green′s Function and Newman Product method. For the sake of quick calculation, two expressions of source functions are provided. With the convolution and the Laplace numerical transformation and its numerical inverse, the method of calculating sandface pressure is given, which avoids solving mathematical problems with complicated inner condition. Calculating results obtained by this method are compared with those given by conventional methods which shows this method is valid and convenient for vertical and horizontal well seepage in single porous medium.
