摘要:
凝析气藏不同于一般的溶解气藏,用一般的黑油模型计算会导致大量凝析油滞留地下,而用组分模型又过于繁琐。针对凝析气藏在开采时会析出凝析液的特点,考虑石蜡的沉积,推导了凝析气藏气液固三相渗流的数学模型。在黑油模型的基础上加入有机固相沉积的组分,对气液固三相渗流数学模型进行了求解并编写了上机程序。根据大港千米桥凝析气藏的实际数据计算,表明凝析气和石蜡的析出会造成近井地带的压力急剧降低,凝析油的分布呈"三区"分布特征。该研究对于掌握凝析气在地下的渗流动态具有重要意义。
Abstract:
Condensate gas reservoirs are different from the normal dissolved gas reservoirs.Much condensate oil will be left underground if the normal black oil model is used for calculation.But it costs too much to use the compositional model.So a mathematical model of gas-liquid-solid three-phase flow is derived in this paper based on the precipitation of condensate liquid while exploiting condensate gas reservoirs and the precipitation of paraffin.On the basis of the black oil model,the mathematical model is resolved and a computer program is written.Using the production data of Qianmiqiao condensate gas reservoir in Dagang Oilfield,a conclusion is drawn that the precipitation of condensate gas and paraffin will result in the abrupt loss of pressure near the wellbore.What’s more,it is shown that the condensate oil features in three-area distribution.
