【摘要】 本文根据干酪根元素、热重、扫描电镜、热谱、红外光谱、顺磁共振等项目的分析研究认为,苏北东台坳陷下第三系主要生油岩阜二段和阜四段的母质类型是Ⅱ型;泰州组、戴南组、阜一、三段是次要生油岩,母质类型多属Ⅲ型或Ⅱ、Ⅲ型兼有。通过方法比较指出,干酪根元素分析是确定母质类型的主要指标,其划分母质类型界限清楚,有普遍使用意义。本文还用实验模拟、热重、热谱等方法测定了干酪根的生油潜量,并与蒂索确定的生油潜量进行了比较研究。认为实验模拟和热重分析数值近似,资料可信度较高,但模拟法较为复杂,而热重法简便实用。测试结果,Ⅱ型干酪根的生油潜量为0.3克_碳/克_有机碳,Ⅲ型.为0.1克_碳/克_有机碳。更多还原

【Abstract】 According to the data from the analysis of kerogen,i,e.elemental analysis,thermal gravity analysis,Rock-Eval analysis,IR spectra,ESR spectra and SEM examination, the 2Nd and 4th members of the Funing formation of the Lower Tertiary, coNtaining Type Ⅱ organic matter,are ranked as main source rocks.The Taizhou formation,Dainan formation,the 1st and 3rd members of Funing formation with their organic matter mostly of Type Ⅲ or partly Type Ⅲ partly Type Ⅱ are ranked as subordinatesource rocks.Compared with other methods,the elemental analysis data of kerogen can be served as the main parameter for identifying the type of source material owing to its clearcut type classification and its wide applicability. By using simulation experiments,TGA method and Rock-Eval analysis,the pote- ntial of kerogen for oil generation was measured and compared with that determi- ned by Tissot.The results show the approximation of the data of TGA to those of simulation experiment,implying their relatively high reliability.The simulation experiment is somewhat more complicated,while TGA method is rather simple, hence better practicability.The measured potentital of Type Ⅱ kerogen is 0.3g.C/g. Corg,and that of Type Ⅲ is 0.1 g.C/g.Corg.更多还原
