   对致密气藏进行常规产能分析时,由于渗透率极低,要达到稳定通常需要很长的测试时间。对此提出了致密气藏的产能分析方法,建立了气井产能分析的最优化模型,并讨论了该模型的求解方法,还建立了地层压力不确定时的气藏产能分析模型。通过实例分析发现,运用提出的致密气藏产能分析方法求出的结果与实测数据非常吻合。

When studying the conventional deliverability analysis of

the tight gas reservoir, the tight gas reservoirwill always need

long test time to stabilize due to its low permeability. This

paper p resents the method of deliverability analysis for the

tight gas reservoir, sets up the op timum model of deliverability

analysis for gas wells, and discusses the solution of this

model;moreover, this paper also constructs the model of the

deliverability analysis for gas reservoir when the formation

p ressure is not stable. The case analysis p roves that the results

of the deliverability analysis for gas reservoir p resented by this

paper agree wellwith the actuallymeasured data.
