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一一切必要元素以及这些元素之间有效的配置结构,其中的元素是烃源岩、输导体系和圈闭。塔中早古生代和晚古生代成藏体系的烃源岩、输导体系和圈闭均为分离状,都属于三位成藏体系,但前者的油气来源单-(单源),后者的油气来源多样(多源),故两者分别被称之为塔中早古生代单源三位成藏体系和塔中晚古生代多源三位成藏体系。烃类流体主要来源于塔中北斜坡烃源岩,烃类流体沿不整合面和志留系砂岩层侧向运移,再沿断裂向上运移,分别为早古生代和晚古生代成藏体系提供油气。

Abstract: Petroleum accumulation system is a natural subsurface petroliferous system which includes all the essential elements such as source rock, flow-conducting system and trap, and the effective configurations among them. The source rock, flow-conducting system and trap of the Eopaleozoic and Neopaleozoic petroleum accumulation systems are isolated in Tazhong area, in which the petroleum of Eopaleozoic comes from single source, whereas that of Neopaleozoic from multiple sources, shaping three-body systems, respectively. The hydrocarbons mainly come from the source rocks in slope of northern Tazhong area by lateral migration along the unconformity and the Silurian sandstone followed by up-ward migration along the faults, finally, entering into the Eo-and Neo-Paleozoic pet roleum accumulation systems in Tazhong area, Tarim basin.

Key words: Tarim basin, Eopaleozoic, Neopaleozoic, petroleum accumulation, analysis
