一、沉积史渤海湾盆地是一个复式叠加型沉积盆地。新生界,中生界,古生界和震旦亚界地层内广泛分布有多套生储盖组合。具有多旋回、多层系和多油气藏类型的含油气盆地的特色。晚元古代(震旦亚代)准地槽沉积发展时期:吕梁运动后,沿着内蒙古陆南缘,张家口-北票深断裂南侧形成一个北东东方向的沉降带,称为燕山准地槽。沉积了晚元古代震旦亚界最厚9400米以碳酸盐岩为主的巨厚沉积。早古生代(下寒武纪-中奥陶纪)地台沉积发展时期:
First, the sedimentary history Bohai Bay Basin is a double superimposed sedimentary basin. There are a number of reservoir-cap assemblages widely distributed in the Cenozoic, Mesozoic, Paleozoic and Sinian strata. Features of petroliferous basins with multi-cycle, multi-layer and multi-reservoir types. During the Late Proterozoic (Sinian Asia) quasi-geosyncline depositional development: After the LüLiang movement, a northerly eastward subsidence zone was formed along the southern edge of Luneng in Inner Mongolia and Zhangjiakou-Beipiao deep fault, which is called Yanshan quasi-terrane. Sedimentary Late Sinian Sinian sub-maximum thickness of 9400 meters to carbonate-based thick deposit. Early Paleozoic (Cambrian - Ordovician) platform deposition period of development:
