| 摘 要： | 气井产量取决于井底流动压力，所以气井产能方程应该能够直接描述流压与产量的关系。文中基于气井二项式产能方程，提出了可以直接反映流压与产量之间关系的二元回归形式的产能方程模型。介绍了该模型的基本原理并进行了实例分析。该模型可以预测地层压力。

| Abstract: | For gas well production depends on bottomhole flowing pressure.The relation between flowing pressure and production can be directly reflected by gas well productivity equation. According to binomial productivity equation for gas well,a productivity equation model of binary regression is proposed,which can indicate the relation between flowing pressure and production. This paper introduces basic principle of the model and does example analysis. The model can predict reservoir pressure. |
