摘要： 对呼图壁呼2井区气藏的凝析气高压PVT实验数据进行拟合计算,确定了适合描述该气藏流体相态行为的流体组分特征参数;利用地质研究成果所确定的单井各层物性参数,结合构造形态和井位,建立了相应的三维地质模型;在完成了储量拟合以后,针对气藏生产历史数据进行历史拟合研究,取得了令人满意的拟合效果;为了论证呼图壁呼2井区气藏合理开发技术指标,从9个方面对该气藏未来的开发指标进行了数值模拟研究,主要结论是:该气藏现有7口采气井能满足生产任务要求,气藏按150×104m3/d产能设计是合理的,稳产年限从2003年1月算起为8年,到2020年天然气和凝析油的采出程度分别为70.7558%和44.1564%.

Abstract: The high pressure PVT experiment data of Wellblock Hu-2 condensate gas reservoir in Hutubi gas field are calculated. The fluid compositional characteristic parameters used for describing the phase behavior of this reservoir are determined. According to the petrophysical parameters from individual well and layer integrating with structure geometry and well location, a 3D geologic model is developed. Following its reserves matching, study of the gas production history matching is made, obtaining satisfactorily matched results. For demonstrating the technical parameters for reasonable exploitation of Wellblock Hu-2 gas reservoir, the numerical simulation research in nine aspects is conducted. The main conclusions are that seven gas wells can meet the production requirement, and productivity plan of 150x104m3/d is reasonable, with stable production period of eight years ranging from Ian., 2003 to Dec., 2020. It is estimated that recovery percent of natural gas and condensate will reach 70.7558% and 44.1564%, respectively, by the end of 2020.

Key words: Hutubi gas field, gas reservoir development, gas condensate, history match, numerical simulation
