| 摘 要： | 应用激光－诱导荧光、环境扫描电镜全岩热模拟实验技术等，对鄂尔多斯盆地奥陶系岩心样品进行了沥青判识及定量、有机质生气过程的可视化模拟以及产气潜力等研究。奥陶系岩中普遍存在的沥青及有机质生气过程的可视化动态模拟结果证实，烃源岩在地质历史中曾经生排烃；烃源岩产气率大于自身的吸附气量，有效气源岩。推测在鄂尔多斯盆地奥陶纪纪海进期沉积的地层中可能发育优质气源岩。 |

| Abstract: | Laser-fluorescene, environmental scanning electron microscope and rock thermal simulation techniques have been used to identify and quantify bitumen, to evaluate the genetic potential and to imitate the visible gas generation process of organic matter from Ordovician rock in Ordos basin. The conclusions have proved that the source rock had generated and expelled hydrocarbon during the process of geologic history by the existence of bitumen in rock and the visual simulation of organic matter. The source rock is effective only if the amount of gas generated in Ordovician rock is greater than that of the adsorbed by itself. Authors propose that the source rock with high abundant organic matter developed in transgressive sequence of Ordovician in Ordos. |
| Keywords: | Ordos basin Ordovician source rock bitumen validity environmental scanning electron microscope visual simulation |
