摘要: 运用旋回层序地层学的方法,利用钻井、地震、岩心和各种分析资料,对北黄海某研究区块的层序进行了综合分析研究,在中生代上侏罗统-新生代渐新统识别出11个中期基准面旋回,并与相应三级层序对应,从下到上依次命名为层序Ⅰ-层序Ⅺ,从而建立了北黄海某研究区块的高分辨率钻井层序地层格架。在此基础上,通过对北黄海盆地构造发育过程的认识,以及钻井、地震等资料提供的信息,进一步对研究区中新生代地层的沉积特征进行了研究分析,认为研究区主要发育了侏罗系、白垩系两套勘探层系,纵向上主要有三套有利的储盖组合的结论,这对研究区油气分布规律进行研究有重要的指导意义。Abstract: Utilizing the method of cycle sequence stratigraphy and using actual data such as drilling,seismic and core,the authors analyze block X area in the North Yellow Sea basin. We have identified in the upper Jurassic of Mesozoic-Cenozoic Oligocene strata 11 mid-term base-level cycles,corresponding to a three-tier sequence,composed of sequence Ⅰ-sequence Ⅺ from bottom to up and we thus could establish a high-resolution drilling sequence stratigraphic framework in the study area. Based on this result and the understanding of the North Yellow Sea basin evolution and development,together with information from drilling, seismic and so on, we further study the sedimentary characteristics in the Mesozoic and Cenozoic strata of the area,and come to the conclusion that there are two sets of exploration layers and three sets of favourable reservoir and seal associations in the area. These are of important guiding sense to study the petroleum trap distribution in the study area.
