摘　　要： 琼东南盆地是南海北部被动大陆边缘的新生代含油气盆地,具典型断坳双层结构,其油气运聚分布规律及成藏条件与中国东部陆相断陷盆地类似,油气成因类型多,油气源复杂,且不同区带油气运聚规律及成藏组合与成藏控制因素均差异明显。根据本区油气成因类型及2类主要油气成藏组合(自生自储,下生上储)的运聚成藏模式特征,剖析与探讨油气运聚成藏规律,指出近期油气勘探方向,为提高油气勘探成功率、降低勘探风险提供决策依据。 Qiongdongnan Basin is an oil-bearing fault-depression structural basin developed in Cenozoic at the passive continental margin of the South China Sea. The hydrocarbon migration, accumulation and distribution were analogous to the continental fault basin in East China. The hydrocarbon migration, accumulation, distribution, reservoir combination and accumulation controlling factors are quite different for zones because of various hydrocarbon origins and complex source rocks. According to the type of hydrocarbon origins and the 2 reservoir combination modes, ＂ self-generation and selfstorage＂ and ＂lower-generation and upper storage＂, hydrocarbon migration and accumulation rules are discussed to provide basis for lowering exploration risks.
