气井产能方程能够直接描述井底流动压力和产量的关系。在建立气井产能方程的传统方法中,需要关井测试气藏的地层压力。本文不需要地层压力,只通过井底流压——产气量数据,利用线性回归方法,即可建立二项式产能方程。通过与常规的作图法和最小二乘法对比表明,本方法可靠。
Gas well productivity equations directly describe the relationship between bottom hole flow pressure and production. In the traditional method of establishing the gas well productivity equation, the formation pressure of the well to be tested is required. This paper does not need formation pressure, only through the bottom-hole flow pressure - gas production data, the use of linear regression method, you can establish binomial productivity equation. The comparison with the conventional mapping and least squares shows that the method is reliable.
