【摘要】：以柿庄地区的常规测井曲线为基础,结合钻井资料和野外露头,对柿庄地区沉积微相进行了划分,总结出了用于沉积微相识别的测井曲线特征。同时,在高分辨率层序地层格架下,研究了太原组和山西组沉积微相的平面展布特征及沉积演化模式。结果表明:研究区太原组可划分为5个四级层序,发育障壁-泻湖-潮坪沉积体系;山西组可划分为3个四级层序,发育下三角洲平原沉积体系,以分流河道和分流间湾为主体;研究区太原组和山西组经历了3个沉积演化阶段,即大规模海侵阶段、缓慢海退阶段、明显海退阶段。
[Abstract]:Based on the conventional logging curves in Shizhuang area, combined with drilling data and outcrop, the sedimentary microfacies in Shizhuang area were divided, and the characteristics of other log curves used for sedimentary microacquaintance were summarized. Under the high-resolution sequence stratigraphic framework, the plane distribution characteristics and sedimentary evolution model of sedimentary microfacies in Taiyuan and Shanxi formations are studied. The results show that the Taiyuan formation in the study area can be divided into five four-order sequences. The Shanxi formation can be divided into three four-order sequences, and the depositional system of the lower delta plain is developed, with distributary channel and interdistributary bay as the main body. The Taiyuan formation and Shanxi formation in the study area have experienced three stages of sedimentary evolution, that is, large-scale transgression stage, slow regression stage and obvious regressive stage.
