根据最新调查资料并结合区域构造背景。通过盆地结构与控盆断裂、沉降曲线类型、沉积相特征、含油气系统、地壳结构类型、大地构造环境以及围区盆地类型等方面的综合分析,探讨了北黄海中、新生代盆地的原型性质。研究表明,北黄海盆地的原型在晚侏罗世—早白垩世以及古近纪均属于区域隆起背景之上发育的陆内断陷盆地,可分别称之为中生代陆内断陷盆地和古近纪陆内断陷盆地;新近纪则属于坳陷型盆地,可称之为新近纪坳陷型盆地。综合考虑控制中生代与古近纪沉积的断层的继承性和差异性、沉积相带和沉积中心的迁移性、沉积范围的比较接近特点、自成体系的含油气系统以及新近纪坳陷型沉积与前两者的垂向叠置关系等,将北黄海中、新生代盆地确定为叠合型盆地。
According to the latest survey data and combined with regional tectonic setting. Through the comprehensive analysis of the basin structure and the control basin fault, the sedimentation curve type, the sedimentary facies characteristics, the petroleum system, the crustal structure type, the tectonic setting of the tectonic environment and the types of the basin area, the prototype properties of the Mesozoic and Cenozoic basins in the North Yellow Sea . The study shows that the prototypes of the North Yellow Sea Basin belong to the intracontinental rift basin developed over the regional uplift background in the Late Jurassic-Early Cretaceous and the Paleogene. They can be respectively called the Mesozoic intracontinental rift basin and the ancient Ji Lu intracontinental rift basin; Neogene belongs to the depression basin, which can be called Neogene depression basin. Considering the succession and difference of the faults controlling the sedimentation of the Mesozoic and Paleogene deposits, the migration of sedimentary facies belts and sedimentary centers, and the relatively close depositional characteristics of the sedimentary facies, the self-contained petroleum systems and the sedimentation of the Neogene depression Vertical superimposed relationship between the former two, the North Yellow Sea, Cenozoic basin identified as a superimposed basin.
