| 摘 要： | 通过分析已有样品的有机碳含量、生烃潜量、氢指数、最大热解温度及镜质体反射率Ro等参数,对青东凹陷古近系烃源岩有机质丰度、有机质类型和有机质成熟度进行研究。该区沙三段、沙四段为好-非常好的烃源岩,东营组、沙一段、沙二段烃源岩类型以腐殖型(Ⅲ型)和混合型(Ⅱ型)为主,而沙三段、沙四段烃源岩类型主要为腐泥型(Ⅰ型)和混合型(Ⅱ1型)。沙三段、沙四段烃源岩,已进入低熟-成熟期,具有较强的生烃能力。

| Abstract: | Based on the analyses of such parameters as total organic carbon,S1＋S2,IH, Tmax,Ro and the like,organic abundance,organic types and organic maturity of Eogene hydrocarbon source rock in Qingdong Sag have been studied.Sha3,Sha4 produced good-better hydrocarbon source rock.The types of hydrocarbon source rock of Dongyin formation, Sha1,sha2 mainly comprises typeⅢand typeⅡ,while Sha3,sha4 mainly comprise typeⅠand typeⅡ1.The carbonate source rock of Sha3,Sha4 has stepped into low-mature to mature phases,fairly capable of producing hydrocarbon. |
