摘要
油气系统（ＰｅｔｒｏｌｅｕｍＳｙｓｔｅｍ）是９０年代石油地质学的重要进展，但在多旋回构造变动区，国外盛行的油气系统定义及成因分类法多不适用，必须修正，应该考虑多期成藏、晚期成藏、纵向混源等特点。根据中国南方海相地层发育区的多旋回构造变动特点，创立了油气系统的历史—成因分类法，既要从成因角度划分原型盆地的油气系统，也要从历史演化角度分析油气系统形成后的动态变化，最后根据实际区域地质特点确定出可操作的油气系统类型。并以中国南方志留系—石炭系油气系统为例说明之。
The introduction of petroleum system is an important advance of petroleum geology in 90'.But its concepts and genetic cla ssification widely used overseas are not applicable for analyzing the region of polycyclic movement,and factors such as multiphase pool forming,paulopast pool forming and vertical mixing source should be revised in this case.In this paper,a historic genetic classification of petroleum system is put forward in view of the special feature of marine sequences in South China.In the region which has undergone polycyclic tectonic movements,it is necessary to divide petroleum systems of primary basin genetically,analyze dynamic changes after the formation evoluted,and then determine operative types of petroleum system based on regional geological characteristics.The Silurian Carboniferous petroleum system in South China is taken as case study.
