摘　　要：该文从输导体系的分类、输导性能研究入手,将油气运移方式分为直接运移和间接运移方式,并进一步对间接运移方式进行了分类。对输导体系的输导性能在空间上的不均一性及其影响要素(孔渗性的作用、断层的作用、天然裂缝的作用、不整合面的影响和作用)也进行了分析,同时对输导体系的输导性能随时间变化的规律性也进行了探讨。在宏观时间尺度内输导体系的输导性能是幕式变化的,在微观时间尺度内各种不同的输导体系则表现出随时间变化而异的特点。在同一个含油气系统中,各种类型的输导体系必须在时空上相匹配,才有可能形成具经济价值的油气聚集与成藏。Petroleum migration was classified into direct and indirect migration based on the studying of its migrating characteristics and the classification of passage system. And the indirect migration was further classified. The inhomogeneity of migrating capabilities of a passage system in spatial and its influent factors such as porosity, permeability, faults, crude fractures and unconformity were analysed. It could be concluded that the migra ting capabilities of a passage system was episodic in very long time, but different passage system showed varied properties in a short time. Only diversified types of passage system were placed in their suitable locations temporally and spatially, could a commercial hydrocarbon accumulation be formed.
