| 摘 要： | 应用多项分析测试技术，对南祁连盆地热水－默勒地区上三叠统可能烃源岩进行了有机质丰度，类型、成熟度、有机母源和沉积环境等方面的分析。该区上三叠统可能烃源岩为前三角洲和湖沼相的泥质岩沉积，其有机质丰度较高，有机质类型为腐殖型和混合型，主要处于成熟阶段，有机母质主要为高等植物和一定数量的藻菌类低等水生生物的贡献。综合分析认为该套地层具有一定的生烃能力，其中一些层段生烃潜力较大。

| Abstract: | Source,depositional environment and thermal maturity indicators from Upper Triassic potential hydrocarbon source rock in Reshui-Muole area of the South Qilian basin have been studied by means of biomarker analysis technology and other geochemical methods The potential hydrocarbon source rock,mainly composed of sediments deposited in predelta and lake basin bog environment,has a high abundance of organic matter The humic and mixture types of organic matter indicate that they were derived mainly from higher plants with some inputs of lower marine organism Analysis data and related parameters also indicate that the organic matter has developed mature All these suggest that source rocks are developed in upper Triassic strata of the studied area and their oil-generating potential is relatively high |
