  • 简介:基于井核心,薄节和FESEM的观察,把指示物,水库特征和S字4-Esx的页岩油丰富的控制因素与X光检查衍射,物理性质测试和geochemical相结合在Jiyang消沉的3页岩被详细说明分析。研究证明碳酸盐和泥土矿物质在页岩被统治。根据三角图表,TOC内容(2%和4%),碳酸盐和泥土矿物质,九张岩相被识别了。水库空间类型富于页岩,在哪个,把压成薄片的破裂,再结晶intracrystalline毛孔和器官的毛孔是高质量的水库空格。页岩油丰富被生产烃的潜力和水库能力主要决定。烃--生产能力被器官的地球化学指示物,为学习区域的特别TOC内容,和器官富人的页岩的厚度控制。水库能力被岩相,TOC内容和结构的活动主要影响。另外,页岩采油被页岩的fracability影响,它被岩相主要控制,结构的活动,形成压力,等等。页岩油水库评估应该集中于TOC内容,器官富人的页岩的厚度,岩相和结构的因素。

  • 简介:古生代的Wufeng-Longmaxi页岩是为在四川盆的页岩气体探索的主要地平线之一。露头,核心和薄节观察,X光检查衍射分析,踪迹元素地球化学和另外的方法被用来理解沉积特征并且在北贵州省在Wufeng-Longmaxi页岩在合适的沉积paleoenvironments识别烃来源岩石。从20~200m和它的Wufeng-Longmaxi形成范围的厚度主要在深海的架上被扔。TOC内容高,直到5.75%。主要非器官的矿物质是由岩屑形成的石英和泥土矿物质,与一点斜长石长石,钾长石,方解石,白云石和黄铁矿。也有源於生物的微晶质的石英。六张岩相被识别了:硅质的页岩,泥土页岩,石灰质的页岩,淤泥的页岩,碳的页岩,和泥泞siltstone。用生物Ba,V/(V+Ni),TOC,V/Cr,B,Sr/Ba和另外的指示物,我们估计Wufeng-Longmaxi免职的早阶段发生在强壮的缺氧的条件下面的主要生产率,氧化还原作用条件和paleosalinity和表演,高paleosalinity并且产出一个高TOC内容和优秀潜在的页岩气体来源。缺氧的环境在Wufeng-Longmaxi免职的迟了的阶段被破坏,TOC内容减少了,以便它是可能的是高质量的来源岩石。因为在页岩的关键水库空间,和毛孔主要是mesopose,器官的毛孔行动了,与大多数毛孔直径不到20nm。硅质的页岩让高TOC内容和易碎的矿物质(石英)满足为页岩油和煤气的探索使它成为一个重要探索目标。
