| 摘 要： | 目前，凝析油气井不稳定试并分析通常是把凝析油产量折算成气产量，然后用气井的解释方法来解释。本文从凝析油气藏径向渗流的微分方程组出发，得到了单相流分析法。计算油、气相流度和总流度所采用的地下产量应分别为（Q0－RvQg）B0／（1-RsRv），（Qg－RsQ0）Bg／（1－RsRv），［（Q0－RvQg）B0＋（Qg－RsQ0）Bg］／（1－RsRv）；即使在地层中仅存在气相的凝析气井的试并分析中，在计算气相流度或有效渗透率时，也不应把凝析油产量折算成气产量。

| Abstract: | The gas phase is consisted of both gas and oil components in condensate gas reservoirs while that instead of singegas phase in black oil reservoirs. The method of single phase flow is presented in terms of governing equations ofthe radial flow in oil gas reservoirs. The subsurface rate used in calculation of total and single gas/oil mobilityshould relatively be folowing: (Q-Rvh)BV/(1-RsRv), (Qs-AsQ0)Bs/(1-RsRv), (Q0-RvQg)B0 (Qg-RsQ0)Bg]/(1 -RsRv). The condensate rate may not be equivalently converted to a gas rate When calculatinggas mobility or effective Permeability even if only the gas phase saved in the formation of condensate wells. |
