摘要
本文采用了三种方法对直井多层合采产能进行评价,分别为堆积叠置型砂体气藏直井产能方程法、多层合采气藏不稳定试井法和储层与井筒耦合的不稳态产能计算方法。针对不同气藏,选择合理的产能计算方法,提高多层气藏的开发价值。
Three methods are used in this paper for the evaluation on capacity of vertical well multilayer commingled production,which includ th vertical w ll produc vi y equation o accumulation of superimposed sand gas reservoir,unsteady well testing for commingled gas reservoir and a computation method for unsteady productiv tycoupling reservoir with wellbore.Therefore,the appropriate calculation method fo production capacity is selected to im ve the explo tatio valu of multilayer gas reservoir in terms of different gas reservoir.
