Abstract：After the "South Sea movement" in the late of Early Oligocene,most parts of the Pearl River Mouth Basin are shallow-water shelf deposits,transiting from continental environment to marine environment.After "Baiyun movement" at the end of Paleogene,the basin wholly entered to marine environment as the sea level rose.Different tectonic evolution that the Pearl River Mouth Basin experienced leads to different types of reservoirs,which mainly developed in late Oligocene-Quarternary marine-continental and marine facies.Reservoirs in shallow water include delta deposits,shelf sand ridges,coastal sandstone,bioreefs and fan deltas,of which the shelf delta-coastal system and bioreef deposits have been found as the most important producing layers of the oil fields.Reservoirs in deep water include submarine fans,shelf-margin deltas and platform-margin slope fan.Among these deposits submarine fans in the LST as well as shelf-margin delta are the most potential exploitation objects in the deep water.
