| 摘 要： | 在漫长的地质历史中,中国南方海相层系经历了多旋回构造运动与强烈后期改造。印支运动以来,多期沉降与隆升及其地区差异性表现产生了"早降晚抬"和"早抬晚降"两大类6种形式的埋藏演化史类型。受埋藏史类型控制,南方各地区不同层系烃源岩的生烃演化史存在明显差异性。按生烃过程是否连续及成熟演化明显暂停前是否已达到或超过生烃高峰期,将南方海相烃源岩的生烃演化过程归纳为连续生烃模式、二次生烃模式和晚期生烃模式等3种类型。

| Abstract: | The marine strata in southern China underwent polycyclic tectonic movement and intensive late reworking in long geologic times.The differences of multistage subsidence and uplift,and regional erosion and deposition in different parts of southern China since the Indo-China movement have led to the delineation of six types of burial history,which may be separated into two groups including the "early subsidence-late uplift" and "early uplift-late subsidence".As a result,there are marked differences in hydrocarbon generation and evolution in different parts of southern China.According continuity of the hydrocarbon-generating processes,the hydrocarbon generation and evolution may be involved into three models,namely the continuous hydrocarbon generation,secondary hydrocarbon generation and late hydrocarbon generation. |
