摘要
对大港探区中生代残留盆地进行原型盆地恢复．原型盆地可分为：早中侏罗世坳陷型盆地，晚侏罗至早白垩世断坳共存盆地及晚白垩世热坳陷盆地．中生代原型盆地分布方向为ＮＥ－ＮＮＥ向，分布范围有限，且沉积厚度较小。
The primary basin of Jurassic and Cretaceous period in Dagang exploration area is recoveried basised on previous data. The evolution of Mesozoic basin in Dagang exploration area includes three stages: early middle Jurassic, late Jurassic early Cretaceous and late Cretaceous period. The basin in Dagang exploration area is depression type which trending is NNE NE. Late Jurassic early Cretaceous basin is extension, which trending is NNE NE and WE NWW. The late Cretaceous basin is sag after extension. It is divided into two parts by Qikou Yanshan Yingang Fault Zone. The formation of basin is the result of the combining action of two tectonic dynamic systems which is subduction of the Izanaqi Plate toward European Asia Plate during Jurassic and Cretaceous Period in oblique direction and collision of North China Plate and Yangtze Plate in the late Triassic Period under the dominantly compressive stress field.
