摘要: 烃源岩与输导体系的配置组合,按二者的接触关系,可分为垂向、侧向和交错接触型3种;按输导体的类型不同,可分为源岩—断层、源岩—连通砂体和源岩—不整合3种。分析了形成各类组合的控制因素,指出了源岩与输导体系配置规律的研究意义。不同的配置组合油气运移方式、运移效率以及形成油气藏的类型都存在一定的差异,并最终导致油气空间分布的不同特点。济阳坳陷临南洼陷中央隆起带源岩—断层配置组合决定了油气垂向优势运移,而夏口断裂带源岩—连通砂体配置组合决定了油气横向优势运移。Abstract: The configuration of source rocks and transportation system can be divided into three types of vertical contact,lateral contact and staggered contact according to their contact relationship,and can also be divided into three types of source rocks-fault,source rocks-connected sand bodies and source rocks-unconformity according to different hydrocarbon migration system. The control factors forming different combination and important effects on configuration rule of hydrocarbon source rock and transportation system were summarized.In different configuration combination,there are some difference on hydrocarbon migration fashion,migration efficiency and forming-pool types,which made different characteristic of spacial distribution of oil and gas.The configuration between source rock and fault controlled vertically dominant petroleum migration in central up-lift belt of the Linnan Sag,the Jiyang Depression of the Bohawan Basin.The configuration between source rock and connected sand bodies controlled laterally dominant petroleum migration in the Xiakou fault zone of the Jiyang Depression.
