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。
Based on the conventional logging curves, drilling data and field outcrop, this paper presented a wel l logging interpretation model of sedimentary micro-facies in study area and, analyzed the deposition distribution and sedimentary model of sedimental micro-facies of Taiyuan Formation and Shanxi Formation under the high- resolution sequence stratigraphy framework. Taiyuan Formation was divided into five four-level sequences, and developed barrier bar-lagoon-tidal flat sedimentary system. Shanxi Formation was divided into three four-level sequences. Lower delta plain was characterized by distributary channels and distributary bays was the main body in study area. Taiyuan Formation and Shanxi Formation experienced three sedimentary evolution stages:large-scale transgression phases, slow regressive phases and obvious regression phases.
