| 摘 要： | 本文系统地介绍了盖层封闭能力研究和评价方法,确定了12项主要参数,并从油气勘探的角度出发,将盖层分类与油气富集相联系,认为区域和地区性油气盖层决定了油气富集的层位和地区,局部盖层封闭能形成油气藏,而临时盖层只有在特定的地质条件下才具有勘探意义。最后以南华北地区上古生界盖层评价为例,说明了盖层研究在油气勘探中的意义,并提出了具体的评价意见。

| Abstract: | This paper introduces the research and evaluation methods to caprock seal capacity, and the necessary 12 critical parameters. For hydrocarbon exploration, caprocks are further classified into different types according to their relationship with hydrocarbon accumulation. Basinwide caprock and regional caprock are the factors affecting formation and location of hydrocarbon accumulation. Local caprock seal can form traps ; while temporary caprock has little exploration value except under special geological circumstances. The significance of our research is illustrated with the evaluation of the upper palaeozoic caprock in southern North China. |
