摘要
利用气井产能试井资料确定气井二项式产能方程的常规方法是作图法和最小二乘法 ,本文不需要地层静压 ,只通过井底流压—产气量数据 ,利用线性回归法 ,即可建立二项式产能方程 ,实例分析对比表明 ,本方法准确。
The constructive method and least square method are the conventional methods for establishing the binomial deliverability equation of gas well by use of gas well deliverability test materials.In this paper,a method for establishing the binomial deliverability equation without the static formation pressure data and only with the bottom hole flowing pressure and gas production data,as well as by using linear regression method is presented.Through analysis,it is shown that this method is accurate and reliable.
