Abstract Nansha area is rich in oil and gas resources. Major medium and large basins were formed in the Cenozoic and deposited continental-transitional-marine facies from the bottom to the top. Different factors controlled the distribution of sedimentary facies in these basins. Clastic deposition was controlled by three palaeo-river systems. One from the orogen in the southern margin of South China Continent controlled fan deltas in Nanweixi Basin and Beikang Basin. Another one on Sunda Shelf controlled deltas in Mekong Basin and Wan′an Basin. The last one from Borneo Block controlled fan deltas and deltas in Zengmu Basin and Wenlai-Shaba Basin. And carbonate deposition is controlled by water and structural conditions. Warm,clean,moderately shallow turbulent environment is conducive to formation and growth of carbonate platform and reef. Various sedimentary facies formed different types of oil and gas reservoirs. Miocene sandstone and carbonate reservoirs are the most important reservoirs and source rocks are distributed with regularity. Drifting blocks controlled hydrocarbon distribution in these basins in Nansha area,forming three sets of source-reservoir-caprock assemblages and three kinds of stratigraphic traps.
