摘　　要：对高邮凹陷陈堡油田原油样品进行轻烃组分、Mango轻烃参数及成熟度的研究。结果表明:原油母源有陆源植物和水生生物的输入,母质类型为混合型;泰一段和赤山组原油具有良好的油源相似性,而阜一段样品K1值与前两者差异较大,比较碳环优势,三环较占优势,说明烃源岩主要由湖相沉积形成;庚烷值和异庚烷值显示,陈堡油田大部分原油为低熟油,少数为成熟油。The composition of light hydrocarbons,the Mango parameters,and thermal maturity about oil samples from Chenbao Oilfield of Gaoyou Sag were researched. The result shows that crude oil’s organic matter sources has terrestrial and water input,its type is mixed mode. The crude oil of Taiyi Fault and Chishan Group are similar in oil sources,while Fuyi Fault’s oil is different from them. Make comparisons with carboatomic ring,the three ring has the advantage,suggesting the source rock fomed from lacustrine sedimentation. The information from heptane value and isheptane value indicates the most crude oil of Chenbao Oilfield is immature oil,while the minority is mature oil.
