The Yinggehai-Song Hong (Y-SH) Basin, located on the northwestern shelf of the South China Sea, is one of the world''s largest pull-apart basins. In order to identify the provenance of the Upper Miocene to Quaternary sediments of the basin, ten sediment samples were collected from drill cores in the Dongfang gas field.
Näe rohkem >>Four gas fields and a number of gas-bearing structures have been discovered in the Yinggehai and Qiongdongnan basins offshore South China Sea. Chemical and isotopic data indicate the presence of at least three genetic groups of gases in these basins: biogenic gas, thermogenic gas, and gases with mixed origin.
Näe rohkem >>Large numbers of gas reservoirs have been discovered in overpressure basins. Fluid charging has a close relationship with paleo‐pressure evolution, affecting the migration of gas reservoirs. To study fluid charging and the related pressure system, we analyzed burial histories and fluid inclusion (PVTx) simulations and conducted basin modeling of the …

Näe rohkem >>Three superimposed pressure systems are present in the Yinggehai Basin, South China Sea. A number of commercial, thermogenic gas accumulations have been found in an area in which shale diapirs occur. Because the reservoir intervals are shallow and very young, they must have filled with gas rapidly.
