通过数值模拟某凝析气藏单井产出特征，定量研究反凝析液对产能的影响。将数值模拟结果与油藏工程产能分析进行对比，结果表明：反凝析液对产能影响严重，对于中高凝析油含量的凝析气藏，由反凝析作用引起的产能损失可达20％以上，主要由于反凝析液占据了多孔介质表面而使储集层渗透率降低，同时反凝析液相的出现和参与流动使气相的相对渗流能力变小。给出了在此情况下的产能方程修正公式，可用于对常规的产能方程进行校正。控制反凝析液析出是提高凝析气藏开采效果的关键。图1表2参4（刘玉慧摘）
通過數值模擬某凝析氣藏單井產齣特徵，定量研究反凝析液對產能的影響。將數值模擬結果與油藏工程產能分析進行對比，結果錶明：反凝析液對產能影響嚴重，對于中高凝析油含量的凝析氣藏，由反凝析作用引起的產能損失可達20％以上，主要由于反凝析液佔據瞭多孔介質錶麵而使儲集層滲透率降低，同時反凝析液相的齣現和參與流動使氣相的相對滲流能力變小。給齣瞭在此情況下的產能方程脩正公式，可用于對常規的產能方程進行校正。控製反凝析液析齣是提高凝析氣藏開採效果的關鍵。圖1錶2參4（劉玉慧摘）

Complicated mechanisms and many influencing factors are involved in developing a condensate gas reservoir. This paper studies the influence of retrograde condensate liquid on productivity based on a single-well radial model. Combined with the productivity equation of reservoir engineering, the conclusions are drawn. It is shown that condensate has a dominant effect on productivity, and the decline of production capacity resulting from condensation could amount to 20% in the case of condensate gas reservoir with medium-high content of condensate, largely because the condensate lessens formation permeability and gas relative permeability. In this case, the productivity equation should be corrected. Two corrective methods are presented in this paper. It is also shown that control of gas condensate forming is one of key factors for developing a condensate gas reservoir.
