| 摘 要： | 本文总结了国内已有文献对反常凝析现象的解释并指出了它们的不足,然后提出了一种新的解释,即立足于超临界流体的性质,把井底条件下的凝析气藏看作溶液体系,利用压力和温度对溶液溶解度的影响来解释反常凝析现象。

| Abstract: | This paper concludes the domestic views of retrograde condensation mechanism and points out their shortcomings.Then a new view is put forward.In the downhole condition,the lighter hydrocarbons are supercritical and can dissolve heavy hydrocarbons.The writer regards the hydrocarbon mixtures as a solution system,so when the pressure or temperature drops,the Solubility reduces and heavy hydrocarbons condensate. |
