摘　　要：有效烃源灶的展布决定了油气勘探的领域。石炭系烃源岩与火山岩密切共生,地震资料品质受火山岩高速带屏蔽等因素的影响,准噶尔盆地克拉美丽气田的烃源灶空间分布范围争议较大。根据地球物理资料和大量的烃源岩分析测试资料,对克拉美丽气田的有效烃源灶的空间分布特征进行了详细的研究。研究表明,滴水泉凹陷、东道海子凹陷和五彩湾凹陷是卡拉麦里山前石炭系烃源岩的3个厚度中心,其厚度均大于450 m.烃源岩有机质类型以Ⅱ型和Ⅲ型为主。成熟-高成熟烃源岩也主要分布在滴水泉凹陷、东道海子—五彩湾凹陷和三南凹陷。The distribution of effective hydrocarbon kitchens determines the target for petroleum exploration.The spatial distribution of Carboniferous hydrocarbon source rocks in Kelameili gas field of Junggar basin is unclear due to its coexistence with volcanic rocks,which leads to the poor quality of seismic data to the further study.Based on the structural pattern determined by geophysical data and the analysis of a large number of source rocks data in this area,this paper rebuilt the spatial distribution of the Carboniferous effective hydrocarbon kitchen.The result shows that Dishuiquan sag,Dongdaohaizi sag and Wucaiwan sag are three sedimentary centers of the Carboniferous source rocks,with individual thickness of over 450 m.The organic matter types are dominated by Type Ⅱ and Type Ⅲ.The matured and highly matured source rocks are also distributed in Dishuiquan sag,Dongdaohaizi-Wucaiwan sag and Sannan sag.
