摘　　要：伊朗Kashan区块是以前寒武系变质岩为基底的中、新生代盆地,通过对露头区中下侏罗统Shemshak组烃源岩的有机质丰度、类型及成熟度等地球化学分析并结合油源对比分析,确定其为有效烃源岩。在此基础上笔者对研究区内的成藏要素演化过程进行分析,认为研究区内的区域石油地质背景有利于油气藏的形成、演化。Kashan区块既存在以Shemshak组为源岩的新近系油气藏,也可存在Shemshak组原生油气藏。The Kashan block is a Precambrian metamorphic-based basin of Mesozoic and Cenozoic. Its source rock of Shemshak formation of Middle-Lower Jurassic on outcrop area is assured to be effective source rock by geochemical analysis of the abundance, type and maturity of organic matter, integrated with oil source correlation. The element evolvement for petroleum accumulation indicates that the regional geological setting in this study area contributes to the formation and evolution of oil-gas reservoir. It is concluded that there exist both Tertiary reservoirs with source rock of Shemshak formation and primary reservoirs of it in Kashan block.
