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。
本文採用瞭三種方法對直井多層閤採產能進行評價,分彆為堆積疊置型砂體氣藏直井產能方程法、多層閤採氣藏不穩定試井法和儲層與井筒耦閤的不穩態產能計算方法。針對不同氣藏,選擇閤理的產能計算方法,提高多層氣藏的開髮價值。

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.
