| 摘 要： | 目前,对麻江古油藏源岩的认识仍存在很大分歧.对研究区沥青与原油进行了岩石热解(Roek-Eval)、饱和烃色谱分析,并测定了正构烷烃单体碳同位素组成.结果显示,麻江、丹寨地区下奥陶统O1h+d的沥青成熟度明显高于凯里地区志留系翁项群(S2W),原油；麻江、丹寨地区O1d+h沥青的Pr/Ph峰面积比值＞1,而凯里地区S2... |

| Abstract: | At present,there still remain disputes about the source rock of Majiang paleo-reservoir.The bitumen and oil seepage in the working area are analyzed by Rock-Eval and saturated hydrocarbon chromatography,and the free carbon isotopic composition in n-alkane of them are determined.The results show that the maturity of bitumen in O1d+h Formation in Majiang and Danzhai is higher than that of oil seepage in S2W formation in Kaili.The Pr/Ph ratio of bitumen is >1,but that of oil seepage is <1.The free carbon isoto... |
| Keywords: | paleo-reservoir source rock Pr/Ph n-alkane carbon isotope |
