摘要
凝析气相态实验及全组分模拟分析是合理开采凝析气田和提高凝析油采收率的关键。凝析气相态实验分析能直接得出流体的物性参数 ,但并非能测定所有成分的参数。对相态实验不能测定的成分 ,可根据已测参数确定合适的流体相态模型 ,模拟计算出由实验方法不能测定的参数。全组分模拟能精确地模拟不同凝析气藏开采过程中油、气两相组分的瞬间变化、井流物中重组分含量以及一定分离条件下采集到的凝析油量。
Phase behavior experiment and full composition simulation analysis of condensate gas is the key of producing condensate fields rationally and enhancing condensate recovery. Phase behavior experiment analysis of the condensate gas can determine fluid property parameters directly but not its all components. These undetermined parameters could be calculated by the simulation on a suitable phase behavior model constructed from the measured parameters. The full composition simulation can accurately simulate the instantaneous changes of oil and gas components, heavy component contents of the fluid in wells and the condensate that is collected under certain separation condition in the recovery process of various condensate gas reservoirs.
