THE PETROLEUM SYSTEM AND EXPLORATION PROSPECT IN THE EAST OF NORTH YELLOW SEA BASIN

The North Yellow Sea Basin(called West Korean Bay Basin in the eastern Korean region)is one of the sedimentary basins distributing along the Qingchuanjiang fault zone where there are thick Meso-Cenozoic sedimentary rocks.There are a series of Meso-Cenozoic sedimentary basins,such as Anzhou Basin,Bohai Bay Basin,Laiyang Basin and South Yellow Sea Basin in the vicinity of the North Yellow Sea Basin.The basins mentioned above belong to Meso-Cenozoic superimposed basinS which display great petroleum prospects.Huge faults,such as Tanlu Fault,Qingchuanjiang Fault and Linjinjiang Fault,have close relationship with petroleum migration and accumulation in the North Yellow Sea Basin.Based on the integrated researches on reservoir,oil generation and trap types,the petroleum prospects of North Yellow Sea Basin is determined.
