摘要
澳大利亚西北大陆架油气主要分布在三叠系油气成藏组合、侏罗系油气成藏组合和白垩系油气成藏组合中.烃源岩为三叠系泥页岩、侏罗系泥页岩和白垩系泥页岩;区域盖层主要为白垩系页岩.以构造圈闭为主,主要是断块圈闭.生烃高峰期主要在侏罗纪和白垩纪,新生代为生气高峰期,北部生气早于南部.断层是油气运移的重要通道.
Abstract
The hydrocarbons in Australia northwest shelf are mainly concentrated in the Mesozoic plays,which can be divided into Triassic play,Jurassic play and Cretaceous play.The source rocks originated from the shales of Triassic,Jurassic and Cretaceous.The regional cap rocks are mainly a set of the Cretaceous shale.The trap type is dominated by structural trap,including fault block trap and horst trap.Peak of hydrocarbon generation was taken place in the Jurassic and Cretaceous,while peak of gas generation was mainly in the Cenozoic,and the northern part was earlier than the southern part.The fault was important channels for oil and gas migration in it.
