摘　　要：通过对北黄海太阳盆地二维地震资料重新处理解释,系统研究了地层分布及断裂发育,建立了盆地断裂分布格局及构造样式;首次发现太阳盆地中生代发育两个沉积中心:一个位于北部木星拗陷西南部沿盆地西部两条边界断层分布,另一个位于南部天王拗陷中部;结合地层和钻井资料分析了断裂活动期次和特征,揭示中—新生代构造演化经历了3个阶段:晚侏罗世及早白垩世张扭到压扭阶段(燕山运动期);古近纪早期继续压扭抬升、中期张扭、晚期区域挤压抬升阶段(早喜马拉雅运动期);新近纪到第四纪区域沉降阶段(晚喜马拉雅运动期)。为进一步油气勘探工作提供了有价值的参考。By re-processing the 2D seismic data, the layer distribution and fault system of Sun Basin are analyzed in this paper and the construction pattern of fault system in the basin is built. Two sedimentation centers are first discovered, Jupiter Depression sedimentation center and Uranus Depression sedimentation center, respectively. According to layer and logging data, the tectonic evolution of Meso-Cenozoic has gone through Yanshan movement and the early and late Himalayan movement. The three evolution phases are as follows： （1） transtension to compression torsion in Yanshan movement period of late Jurassic to early Cretaceous; （2） continuing compression torsion of early Paleogene, transtension of middle Paleogene, press and uplift of late Paleogene in Himalayan movement period, 3） regional subsiding in Neogene and Cenozoic. The results provide valuable reference for further work of petroleum exploration.
