| 摘 要： | 王府凹陷青一段泥岩为最好生油岩；青二、三段为较差生油岩。与朝阳沟原油和三肇凹陷原油相比，本区原油具有低芳烃、低Ｐｒ／Ｐｈ、高（Ｃ_（２１）＋Ｃ_（２２））／（Ｃ_（２８）＋Ｃ_（２９）），碳同位素偏轻。生物标志物成熟度参数Ｃ_（２９）甾烷（２０Ｓ）／（２０Ｓ＋２０Ｒ）为０．５１～０．５４。油源对比认为原油来自本区青一段泥岩，原油在凹陷内可以从中心向边部作长距离运移。 |

| Abstract: | Mudstone of Qingl member in Wangfu depression is the best oil source rock, Qing2 and Qing3 members are relatively poor oil source rock.Comparing with Chaoyanggou and Sanzhao depression,the crude oil in Wangfu depression bears the characteristics of low aromatic hydrocarbon,low Pr/Ph, high (C21+ C22)/(C28 +C29) and lighter carbon isotope.Maturity parameter of biomarker C29 sterane (20s)/(20s+ 20R) is 0.51-0.54.Oil-to-source correlation suggests that crude oil comes from mudstone of Qingl member in this area and can migrate for a long distance from centre to edge within the depression. |
| Keywords: | Wangfu depression Oil source rock Oil-to-source correlation Hydrocarbon migration Crude oil Organic geochemistry. |
