     In order to direct the petroleum exploration in the southern deepwater area of Qiongdongnan Ba- sin,based on high resolution 3D seismic data,the identification,evolution and main controlling factors of reef in the southern deepwater area of Qiongdongnan Basin were studied. The results show that the seismic features of the reef in this area are mounded reflections,with high amplitude reflections in the bottom and top,but chaotic internal reflections. In local area,it shows symmetrical reflections or onlap reflections on the overlying strata. The seismic reflection characteristics are similar to the reef seismic reflection of LHll 10ilfield. Simultaneously,the reef mainly distributes in the margin or the inner high parts of northeastern carbonate platform. Vertically, the reef has experienced the process of exposing-growing-drowning several times, which is determined by the relative sea level changes. The dropping of the relative sea level causes the accretion of reef towards the sea and the leaching of the earlier reef. While, the rise of the relative sea level leads to the reef migrate toward the structure highs. Additionally, tectonic movement, terrestrial mate- rial supply,paleogeography and paleoclimate also influence the development of reef.
