摘要
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 reservoir will always need long test time to stabilize due to its low permeability.This paper presents the method of deliverability analysis for the tight gas reservoir,sets up the optimum 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 pressure is not stable.The case analysis proves that the results of the deliverability analysis for gas reservoir presented by this paper agree well with the actually measured data.
