摘　　要：利用干酪根的微组分、干酪根元素组成、岩石热解结果和饱和烃色谱特征对潍北凹陷孔店组烃源岩有机质类型进行研究。结果表明,潍北凹陷孔店组烃源岩有机质类型以Ⅰ和Ⅲ为主,潍北凹陷的北部洼陷以I型有机质为主,潍北凹陷灶户断鼻地区有机质类型以Ⅱ2型和Ⅲ型为主。有机质为低等水生物和陆源高等植物混合输入,低等水生物略占优势。Through studying the organic matter types in Weibei sag by Kerogen maceral,Kerogen element composition,Rock-Eval and gas chromatographic analysis of the saturated hydrocarbon,the results show that the organic matter types are complicated and the main types are Type I and Type III.The organic is mainly Type I in northern sub-sag area and Type II 2 and III in Zhaohu area.The organic matter comes form the lower aquatic organisms and land-sourced higher plants,but lower aquatic organisms is slightly dominant.
