Abstract：Many studies have been carried out on the hydrocarbon geologic conditions of Wan'an,Zengmu and Brunei-Sabah basins. However,there are few studies on the difference of hydrocarbon geologic conditions among basins.Based on a lot of previous research results,drilling,seismic data and oil and gas testing data were comprehensively used to analyse the main difference of hydrocarbon ge-ology in the Wan'an,Zengmu and Brunei-Sabah basins in southern South China Sea.The study shows that the Cenozoic of the three ba-sins all developed two tectonic stages,mainly developing marine-land transitional facies and marine depositional environment.Three pe-riods(Oligocene,Miocene and Pliocene)developed two types of source rocks,i.e.the coal measures and terrigenous marine facies,the period of major source rock is gradually new from west to east.Developed two types of reservoirs,i.e.clastic sandstone and carbonate rock,reservoirs distribution may be characterized by near shore sand and distant shore reef,the reservoirs period is gradually new from west to east.There are two combination of source rock and reservoris,i.e.the distant shore self-generation and self-reservoiring and the near shore lower-generation and upper-reservoiring.
