Organic inclusion and hydrocarbon charging events of the Bagung Formation in the Quemoco area, Qiangtang Basin

摘要:
上三叠统巴贡组是羌塘盆地最重要的含油气层系之一，针对盆地东部雀莫错地区的巴贡组储层开展了流体包裹体岩相学、显微测温及显微荧光分析。结果表明，砂岩中的盐水包裹体共记录了4期热流体活动，在第2~3期热流体活动中，检测到了2类含油相包裹体：数量较少的发黄色荧光油包裹体主要分布于石英颗粒内裂纹中，数量较多的发蓝色荧光油包裹体主要分布于石英次生加大边中。根据2类油包裹体的产状分布和荧光光谱特征，综合地层埋藏史和生烃史分析，认为二者共同代表了一次晚侏罗世的油气充注，与盆地中部地区一致。
Abstract:The Upper Triassic Bagung Formation is one of the most important hydrocarbon-bearing strata in the Qiangtang Basin.Based on the analysis of fluid inclusion facies, microscopic temperature measurement and microscopic fluorescence analysis, the brine inclusions in the sandstone of the Bagung Formation in Quemoco area recorded 4 stages of thermal fluid activity, of which the second to the third stage fluid contain two types of oil phase inclusions.In stage 2 to stage 3 of thermal fluid activity, a small number of yellowish fluorescent oil inclusions are mainly distributed in the cracks within the quartz particles, and a large number of blue fluorescent oil inclusions are mainly distributed in the quartz secondary enlarged side.Based on the occurrence and fluorescence spectrum characteristics of the two types of oil inclusions, combined with comprehensive analysis of stratigraphic burial history and hydrocarbon generation history, it is considered that they represent a period of Late Jurassic oil and gas filling, which is consistent with the central basin.
