通过岩心观察 ,结合测井曲线和地震反射资料分析 ,并根据层序地层和层序界面的识别标志 ,建立了苏里格庙地区的层序地层格架 ,并将上古生界划分为 3个二级层序 (超层序组 )和 15个三级层序 ,其中本溪组和太原组的层序具二元体系域结构 ,即由海进体系域和高位体系域组成 ;山西组、石盒子组和石千峰组的层序具三元体系域结构 ,包括低位体系域、湖进体系域和高位体系域。剖析了陆表海浅陷沉积、陆表海碳酸盐岩与碎屑岩混合沉积及近岸内陆河流—三角洲—湖泊沉积超层序组 (或层序组 )中层序的发育特征 ,论述了层序的演化过程。
Based on the analysis of core observation, well logging curve and seismic reflection data, and according to the identification marks of sequence stratigraphy and sequence boundary, the sequence stratigraphic framework of Suligemiao area was established and the Upper Paleozoic was divided into three Second-order sequence (super-sequence) and 15 third-order sequences. The sequence of Benxi Formation and Taiyuan Formation is binary system tract structure, which consists of marine system tract and highstand system tract. Shanxi Formation, The sequence of the box group and Shiqianfeng Formation is ternary system domain structure, including low-level system tract, lake-derived system tract and high-level system tract. The stratigraphic features of the stratigraphic sequence of the surface epicontinental sea sediments, the mixed deposition of carbonate rocks and clastic rocks in the surface sea and the sequence stratigraphy of the inland river-delta-lake sedimentary super-sequence group (or sequence group) are analyzed. Evolutionary process.
