Summary: The evolution of the Proto-South China Sea is influenced by both its paleogeographic location and the history of its oceanic crust, with significant changes in tectonic properties from the Triassic to the mid-Late Cretaceous ultimately shaping the current structure of the South China Sea.

Summary: This study explores the geochemical characteristics and sedimentary controls of coal-bearing source rocks in the Xihu Depression of the East China Sea Basin, identifying a dominance of vitrinite and low-medium abundance of exinite in these Eocene formations. The presence of high total organic carbon content and low maturity stage suggest a potential for oil and gas resources in this region.

Summary: Deepwater oil and gas exploration in the South China Sea is influenced by the geological history of the Paleo SCS and New SCS tectonic cycles, which control the evolution of basins and the generation, migration, and accumulation of hydrocarbons. The source rocks mainly consist of Oligocene coal-bearing deltaic and marine mudstones, which have undergone multiple heating events resulting in the generation of gas and oil. Accumulation of hydrocarbons is primarily controlled by faults, diapirs, and sandstones in large canyon channels, continental deepwater fans, and shelf-margin deltas.

Summary: This study analyzed the characteristics of coal formation in epicontinental sea basins and continental marginal sea basins developed during different time periods. Both types of basins are characterized by thin coal seams, with changes in sea levels being the main controlling factors for coal formation. While similarities were found in continent-sea interactions and coal-forming sedimentary systems, differences were observed in sea level changes, basin structural characteristics, coal seam stability levels, accumulation and aggregation characteristics, and migration patterns of coal-forming materials. In particular, the marginal sea basins in the South China Sea were characterized by strong tectonic activities and complexity, leading to complex coal-forming processes and paleogeographic patterns.

Summary: By investigating the tectonic histories of continental marginal basins in the central-southern South China Sea, it was found that different types of basins have different conditions for hydrocarbon accumulation, mainly controlled by tectonic events. Over time, these basins generally progressed through three developmental stages during the Cenozoic, with varying reservoir characteristics and filling patterns, resulting in different hydrocarbon resource features.

Summary: The Cenozoic sea-land transition in the northern South China Sea controlled the sedimentary filling pattern and petroleum geological characteristics of the northern marginal sedimentary basins. The transgression in the northern SCS showed characteristics of early development in the east and south, and late development in the west and north, influencing the distribution of continent-marine facies and marine facies source rocks. Regional sea-level changes were influenced by both SCS opening and global sea-level changes, leading to the formation of carbonate platforms in the SCS.

Summary: This study systematically analyzed the types, development characteristics, control factors, and distribution prediction methods of coal-measure source rock in marginal sea basins using the Oligocene coal-measure source rock in the Qiongdongnan Basin as an example. It was found that the Oligocene coal-measure source rock in the Qiongdongnan Basin have typical binary structures, with terrigenous marine mudstone greatly expanding the scope of the coal-measure source rock. A genetic model of the energy belt for the development and distribution of coal-measure source rock was proposed based on various control factors, and prediction methods of the distribution ranges of coal-measure source rock were introduced.

Summary: By the end of 2019, over 220 gas fields had been discovered in the South China Sea, mainly composed of alkane gas with majority being coal-type gas. These gas fields are distributed along the northern, western, and southern continental margins similar to beads, with reservoir types including structural, lithologic, and stratigraphic reservoirs. The main hydrocarbon accumulation period for the region was determined to be the late Pliocene-Quaternary Period, with main controlling factors being the development of coal measures, sufficient thermal evolution, and favorable migration and accumulation conditions.
