摘　　要：南亚太地区是指东南亚及澳洲地区,地质构造上位于欧亚板块、印度—澳大利亚板块及太平洋板块交会地带,中、新生代该地区板块构造活跃,经历了非常复杂的构造演化,形成了多种类型的沉积盆地,按其发育的构造位置,可分为三大类沉积盆地:①主动陆缘型盆地,包括弧后盆地、弧前盆地和弧间盆地;②克拉通内部盆地,包括断陷盆地和坳陷盆地;③被动陆缘型盆地。根据对该地区各类盆地油气地质条件及油气发现的分析,认为弧后盆地、陆内断陷盆地和被动陆缘盆地是最有利的含油气盆地。The South Asia-Pacific region mainly includes Indonesia, Malaysia, Brunei, Thailand, Australia, and Papua New Guinea. It lies at the intersection of the Eurasian-Asian plate, Indian-Australian plate and Pacific plate. It underwent complicated tectonic evolutionduring Meso-Cenozoic periods, which resulted in the formation of a variety of sedimentary basins. According to their tectonic locations,all the sedimentary basins are classified into three main types: active continental margin basins, including back-arc basins, forearcbasins and interarc basins; intracratonic basins, including faulted-depression basins and depressed basins; passive continental marginbasins. Based on the analysis of geological conditions for these basins and discoveries, back-arc basins, rift basins of interior continentand passive continental margin basins are considered to be the most prospective ones.
