| 摘 要： | 油气藏油气充注幕次和成藏年龄确定一直是成藏过程研究的热点和核心问题.通过60块流体包裹体系统分析, 结合单井埋藏史投影方法, 分析了三塘湖盆地火山岩油气藏的油气充注幕次和成藏期次, 确定了其成藏年龄, 从而对其油气成藏过程进行了研究, 认为三塘湖盆地火山岩油气藏经历了石炭纪以来三期油气运聚的成藏过程.它们分别发生在259~230Ma、160~134Ma和70~0Ma, 其中早期(海西印支期)油气成藏对盆地深部油气勘探具有重要意义.

| Abstract: | Studies of hydrocarbon charging events and ages have always been the hot and core issues of oil and gas migration and accumulation processes.In this research,systematic fluid inclusion analytical technology,such as fluorescent colors,micro-beam of fluorescent spectrum and the homogenization temperature(Th)of oil fluid inclusion,has been employed to find out that since the Carboniferous,there are three hydrocarbon charging events in the igneous reservoirs of Santanghu basin,and their charging ages are determ... |
