摘要
油气成藏体系是地表以下含油气的自然系统,它包括了形成油气藏的一切必要元素以及这些元素之间的有效配置结构,其中的元素是烃源岩、输导体系和圈闭。油气成藏体系必须具备能够产生任何单一元素所不具备的功能(形成油气藏)的结构。根据独立烃源岩的发育情况及三大元素的匹配组合关系,油气成藏体系可分为单源一位、单源二位、单源三位、二源二位、二源三位及三源三位。每一元素均包含了自身的时间和空间概念,成藏体系的时间也就涵盖了从“源”到“输导”,再到“藏”的基本过程,它们的匹配组合也就具有了表示油气成藏体系在时间和空间上分布规律的属性特征。在输导体系成因分类方案的基础上,提出了输导体系的理论空间配置关系。
Petroleum accumulation system is a natural subsurface petroliferous system which includes all essential elements as source rock, pathway system and trap to accumulate petroleum and their effective configuration. The configuration of petroleum accumulation system must have the function of accumulating oil and gas which can be formed by none of the individual essential elements. Petroleum accumulation system can be divided into one source with one body, one source with two bodies, one source with three bodies, two sources with two bodies, two sources with three bodies, and three sources with three bodies according to source rock and the configuration of essential elements. Petroleum accumulation system involves the whole process of petroleum generation, migration and accumulation. The configuration of the essential elements has the function of indicating space-time regularities of distribution of petroleum accumulation system. The theoretical classification of configuration in space of the pathway system has been put forward on the basis of genetic classification method.
