| 摘 要： | 南陵—无为地区包括无为盆地和南陵盆地两个主要构造单元,下三叠统为其重要的烃源岩层位之一,自下而上划分为殷坑组、和龙山组以及南陵湖组。在巢湖平顶山剖面共采集三个组的样品74块。分析结果表明有机质丰度整体偏低(<0.4%),但有三个层段达到了中等—好的烃源岩标准,累计厚度25～30m。该区有机质类型以腐泥型占绝对优势,且烃源岩整体处在成熟热演化阶段。

| Abstract: | Lower Triassic rock is divided into Yinkeng, Longshan and Nanlinhu Formations from bottom to top, which are the main marine source rocks in Nanling-Wuwei area. By analysis of 74 source rock samples of the three formations collected from Pingdingshan profile at Caohu in Wuwei, the TOC of the rock is generally low(<0.4%) excepting that of three organic-rich beds of rock (accumulated to 25～30m thick) that is over 0.4%, which belongs moderate to good hydrocarbon-generating rocks. The kerogen type of organic matter is predominantly sapropelic and evolution of source rock is during mature stage. |
