摘　　要：本文在分析天然气在多孔介质中高速渗流基本微分方程物理意义的基础上，采用建立非线性规划模型求解方程系数Ａ、Ｂ、Ｃ，并用交会法确定绝对无阻流量。由此便可确定高产气井产能方程。算例分析表明，本文的方法较原有方法更简便、更精确。On the basis of analysing basic differential equation of natural gas rapid percolation in porous media,establishes nonlinear programming model to extract equation coefficient A,B,C.Absolute open flow capacity is determined by using intersection method.Thereby productivity equation of high productivity well is obtained.Calculation results show that the method is simpler and more accurate than the existing one.
