影响气井及凝析气井产能的因素众多，且某些因素的取值存在不确定性，如何全面客观地评价这些因素，对气井及凝析气井无阻流量的确定非常重要。研究引入了基于正交试验的产能参数分析方法，分析并筛选了不易确定的影响产能的主要因素，还分析了各因素对产能影响的权重，为气井及凝析气井产能评价的客观化和全面化提供了新的方法和技术手段。

In the development of gas reservoir and condensate gas reservoir, absolute open flow and reasonable deliverability of single well are very important parameters, which directly affects the feasibility of the development of gas well and condensate gas well and the development scale of the whole gas field. There are many parameters that affect the deliverability in gas well and condensate gas well, and some parameters are uncertain. Howto evaluate these parameters is very important for confirming the absolute open flow of gas well and condensate gas well. An analytic method of deliverability parameter based on orthogonal test is introduced, and some important factors that are uncertain are studied and selected. This study provides a newmethod and technical support for deliverability evaluation of gas well and condensate gas well.
