摘要
叠合复合沉积盆地含油气系统分析必须结合盆地的形成演化,考虑盆地经历的多期次构造-沉积演化、盆地类型、成烃热机制以及组成油气系统的地质要素,明确每一个含油气系统的时空分布和动态演化。四川盆地具有复合含油气系统特征,表现为多个生烃灶在平面上相互叠置和共享运聚通道（断层及不整合面）,共享相同的盖层,存在多个关键时刻,这些关键时刻既具同时性（或相近）,也有先后差异。地史时期的古隆起是多个油气系统早期油气聚集的最佳场所。图4参2（汪泽成摘）
Analysis of petroleum system in the composite petroliferous basin must be integrated with analyses on the basin evolution, multicycle tectonic-sedimentation the basin underwent and basin type, heat mechanism of hydrocarbon forming, and geological elements of petroleum system, clearly indicating the distribution and evolution of each petroleum system in the basin. The characteristics of mutli-source petroleum system mainly include several source kitchens piled up completely or partly and shared the common migration paths and same cap rocks. Some critical moments were in the same period, some of them were not. Paleo-uplifts are favorable area for hydrocarbon early accumulation in multi-source petroleum system.
