摘要: 基于气井稳定产能方程,考虑 影响气井产能的主要参数地层压力地层系数、渗透率,提出气井无阻流量与这些参数的不同组合之间的函数关系,结合长庆气田下古气藏大量产能试井资料,建立其相关曲线,经线性回归分析,得到计算气井无阻流量的三种新经验公式。实例计算表明,新经验产能公式简便易行,计算结果可靠。

Abstract: According to equations for stable gas well productivity, and considering some key parameters affecting a gas well productivity such as formation pressure, formation factor and permeability, this paper proposed functional relations between the non-resistance flow in a gas well and these parameters respectively, and established correlated curves by using a lot of well testing data from Changqing gas field, obtained three new equations for non-resistance flow of gas wells by linear regression analysis. Case calculations show that these equations are simple for application and reliable for results.

Key words: gas well, non-resistance flow, formation pressure, formation factor, permeability, well testing
