基于有效井半径的概念,在Laplace空间,建立了均质、各向同性圆形定压边界油藏中心一口具有井筒储集和表皮效应井的数学模型.并应用AWG数值及演算法,给出了分析该井试井资料的典型曲线.现场实例的应用结果表明.本方法是可行的.
Based on the concept of effective well radius, a mathematic model with wellbore reservoir and epidermal effect well in the center of homogeneous and isotropic circular pressure-bounding boundary reservoirs was established in Laplace space. The AWG numerical and algorithm The typical curve of well testing data is analyzed.The application results of field examples show that this method is feasible.
