摘要
通过油气包裹体的研究 ,对准噶尔盆地腹部石西油田油气藏成藏期次进行了划分 :1侏罗系油藏为一次成藏 ,充注低熟油气 ;2石炭系油藏为多期次成藏 ,主要充注高熟油气。结合区域地质演化特征对油气藏成藏序列分析得出 :来源于二叠系烃源岩的侏罗系油气藏为次生油气藏 ;石炭系油气藏为原生油气藏 。
Pool forming times of Shixi oilfield were divided through the study of fluid inclusion: ① the pool forming time of Jurassic hydrocarbon pool was once and it was filled with low maturity hydrocarbon;②the pool forming time of Carboniferous hydrocarbon pool was more than one and it was mainly filled with high maturity hydrocarbon.Pool forming succession was analysed with evolution characteristics of regional geology.Jurassic hydrocarbon pool that originated from permian resource rock is regarded as a secondary reservoir, Carboniferous reservoir is original one. There is genetic connection between them.
