THE PETROLEUM SYSTEM AND EXPLORATION PROSPECT IN THE EAST OF NORTH YELLOW SEA BASIN
-
摘要: 北黄海盆地(盆地东部朝鲜海域称西朝鲜湾盆地)为浅海大陆架区,属于中朝地台,在其边缘有安洲盆地、渤海湾盆地、莱阳盆地和南黄海盆地,均为古生代、中生代与新生代的叠合盆地,含油气前景较大。盆地周边发育郯庐断裂带、清川江断裂带与临津江断裂带等大断裂带,盆地中油气的生成、运移、储集与保存都和这些大断裂带有密切关系。通过储集条件、油气生成模拟与圈闭条件类比,探讨北黄海盆地的含油气系统特征,并进一步明确其油气勘探前景。Abstract: 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.
