| 摘 要： | 采用GC-MS分析技术探讨了东濮凹陷西斜坡胡状集-庆祖集油田原油芳烃化合物成熟度参数,包括烷基二苯并噻吩系列、脱羟基维生素E和三芳甾烷系列化合物。分析结果表明,芳烃化合物分布特征、脱羟基维生素E的β/α异构体比值、4/1MDBT、2,4/1,4DMDBT比值、C20/(C20+C26)TAS以及三芳甾烷的相对含量均反映胡状集-庆祖集油田二台阶构造带内的原油为烃源岩低熟阶段的产物,而来自长垣断层断裂带和长垣断层下降盘的原油属于烃源岩成熟阶段的产物。

| Abstract: | The characteristic for the thermal evolution of aromatic maturity parameter, such as alkyl dibenzothio-phenes, dehydroxytocopherol and triaromatic-sterane series compounds have been discussed on the basis of GC-MS analysis for the crude oil in Huzhuangji-Qingzuji oil field in west slope of Dongpu depression. The distribution characteristics of aromatic chromatography, the ratio of β/γdehydroxytocopherol,4-/1-MDBT, 2,4- /1,4-DMDBT, C20 / (C20 +C26 ) TAS and the content of triaromatic-sterane series all suggest the crude oil distributed in second step structural derived from low maturity source rocks, whereas the crude oil distributed in Changyuan fault zone and the first step structural derived from maturity source rocks. |
