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%.
The high pressure PVT experiment data of Wellblock Hu-2condensa te gas reservoir in Hutubi gas field are calculated.The fluid compositional char acteristic parameters used for describing the phase behavior of this reservoir a re determined.According to the petrophysi-cal parameters from individual well and layer integrating with structure geometry and well location,a3D geologic m odel is developed.Follow-ing its reserves matching,study of the gas productio n history matching is made,obtaining satisfactorily matched results.For demons trating the technical parameters for reasonable exploitation of Wellblock Hu-2 gas reservoir,the numerical simulation research in nine aspects is con-ducted .The main conclusions are that seven gas wells can meet the production requirem ent,and productivity plan of150×104m3/d is rea-sonable,with stable p roduction period of eight years ranging from Jan.,2003to Dec.,2020 .It is estimated that recovery percent of natural gas and condensate will reac h70.7558%and44.1564%,respectively,by the end of2020.
