| 摘 要： | 中生界侏罗系是鄂尔多斯盆地重要的石油勘探与开发目的层之一，侏罗系油藏受前侏罗纪古地貌影响较为显著。本文通过流体包裹体特征分析、均一化温度测定和包裹体丰度（GOI）分析、定量颗粒荧光（QGF、QGF-E）研究以及储集层自生伊利石K-Ar定年等实验方法和手段的应用，对鄂尔多斯盆地侏罗系油气包裹体特征进行了精细描述及定量化分析研究，揭示了侏罗系油藏形成时间、充注过程及油气包裹体与油气运移、成藏的关系。研究结果表明：侏罗系油藏存在晚期充注，早期充注少或油藏遭受调整，早期生成的烃类现今仅以沥青的形式赋存，现今烃类流体主要为晚期成藏的产物。侏罗系石油大规模充注期为（108.3±2.0）~（116.5±2.0）Ma（早白垩世中期），具有垂向运移聚集的特点。鄂尔多斯盆地侏罗系油藏早期受岩性和构造双重控制，晚期构造活动调整了油气藏的形态及局部富集。侏罗系在晚期成藏过程中没有形成过叠合连片的大规模的油藏，只在局部构造上形成规模较小的“小而肥”的独立油藏。 |

| Abstract: | The Jurassic Yan’an Formation is one of important exploration and development targets in Ordos basin.Through studying characteristics of fluid inclusions,homogenization temperatures,GOI, QGF,QGF E and authigenic illite K Ar dating method,the characteristic of Jurassic petroleum inclusions were fine described and quantitative analyzed.Jurassic reservoir formation time,charging process,oil inclusions and hydrocarbon migration,accumulation relations are revealed.The results showed that there was Late Jurassic reservoir filling, and early filling reservoirs suffer little or adj ustment.Moreover,the early generation of hydrocarbons presented only in the form of bitumen occurrence.The Jurassic massive oil filling period was about (108.3 ±2.0) (116.5 ±2.0)Ma (Early Cretaceous interim)and its accumulation gone from weak to strong,then strong to weak,with episodes of the continuous filling process,with the characteristics of long-distance migration.The Jurassic reservoir was controlled by both lithology and structure in the early stages of hydrocarbon accumulation. Later tectonic activity adjusted reservoir morphology and local enrichment.Late Jurassic reservoir in the process of formation had no overlapped and large-scale reservoirs,but only on the local structure formed smaller independent reservoir. |
