摘　　要：考虑了全部射孔参数、地质因素和工程因素的影响,开发出射孔工程应用软件包WPSYS-A.在有限元数值模型的基础上,运用非线性回归方法精确地描述了射孔参数之间的相互影响。得出了七种格式和相位下的三种不同情况的21个回归公式.在非线性回归方法中,首次引入极限产率比的概念,获得了某些精确解.将有限元模型、工程软件与精确解对比.得出了可靠计算结果.证明该软件能满足工程要求.WPSYS-A software applied to oil well perforation engineering is developed in consideration of more parameters, such as perforation parameters, geological parameters arid technological parameters. Based on the finite element simulation method, ithe 21 regression formulas of 17 phasing under three conditions were established by using nonlinear regression method. The term of maximum productivity ratio is introduced and some analytical solutions ?were obtained. The comparison of analytical solution, finite element solution and engineering software solution is given, and the results shows the high coincidence.
