摘要： 应用流体包裹体测试技术,对苏北盆地两大凹陷不同层位样品进行了成藏流体剖析。包裹体均一温度分布与宿主矿物成岩作用具有正相关关系。烃类包裹体地球化学研究表明,不同地区、不同层位存在母源输入、成熟度变化,多种生物标志物反映出沉积环境以盐度较高的还原环境为主。源岩成烃条件的差异,造成了在同层位油气充注方面,高邮凹陷早于金湖凹陷,同地区阜一段早于其他层位。

Abstract: By means of fluid inclusions testing technique, the reservoir fluid samples from different strata in two sags of Subei basin are analyzed. The homogenization temperature distribution of hydrocarbon inclusions shows positive correlation with the diagenesis of host minerals. Geochemical study of these inclusions indicates that source input and maturity variations occur in different areas and horizons. The multiple biomarkers reveal the reducing sedimentary environment with high salinity. The diversity of hydrocarbon-generating conditions cause that the oil charging period in Gaoyou sag is earlier than Jinhu sag at the same horizon and Fu-1 member is earlier than other horizons or members at the same area.

Key words: inclusion, geochemistry, biomarker, oil charging, source rock
