| 摘 要： | 通过对松辽盆地周边地区野外地质勘查、典型剖面实测、样品采集及实验分析，确定下石炭统鹿圈屯组为吉中磐石地区暗色泥岩发育的重要层位。应用有机岩石学与有机地球化学分析方法对鹿圈屯组海相暗色泥岩进行了特征研究。分析结果显示：鹿圈屯组海相暗色泥岩平均残余有机碳高达1.99%,有机质类型以Ⅱ1-Ⅱ2为主,80%样品镜质体反射率介于2%~4%，处于高-过成熟演化阶段。鹿圈屯组为磐石地区潜在烃源岩层，暗色泥岩地化指标优于松辽盆地晚古生代烃源岩，具有较好的生气潜力。

| Abstract: | Through geological exploration, typical profile measuring, sample collection and experimental analysis, the author confirmed that the Lower Carboniferous Luquantun Formation was the main horizon that contains dark mudstone in the Panshi area, central Jilin Province. Study by organic petrology and organic geochemistry methods show that the average residual organic carbon of the dark mudstone could reach 1.99%; its organic matter type isⅡ1-Ⅱ2; vitrinite reflectance of 80% samples between 2%-4%, and is mainly at high-to over-mature evolution stage. The Luquantun Formation was potential hydrocarbon source rock in the Songliao basin, and the geochemical index of the dark mudstone was better than those of the Late Paleozoic source rocks. It is of high gas-generating potential. |
