高邮凹陷马家嘴-联盟庄地区戴南组构造一沉积体系

沉积过程和构造作用的关系研究历来都是地质工作者进行盆地分析的核心问题，层序地层学的提出与发展将该问题在现阶段已演变为结合构造演化发展，从三维空间整体解剖沉积过程的沉积体系研究，研究结果表明，构造作用是控制陆相断陷盆地沉积体系发育、展布及演化的主要因素之一。该文在岩心观察、野外露头、测井曲线识别及地震资料解释的基础上，将苏北盆地高邮凹陷马家嘴-联盟庄地区戴南组划分为湖泊、湖底扇、近岸水下扇和扇三角洲4种沉积体系，在结合马家嘴-联盟庄地区构造发展演化过程的基础上，分析得出研究区戴南组的沉积体系在纵、横向上受构造控制作用明显。

The tectonic-sedimentary system of the Dainan Formation in Majiazui-Lianmenzhuang region, Gaoyou Sag

The study on depositional process and tectonic action is always a core question for geologists during the basin analysis process. With the sequence stratigraphy development, this question has evolved into the study of sedimentary systems in 3D space integral anatomic sedimentary process combing with the tectonic evolution. The research result shows that tectomc action is an important controlling factor for sedimentary system development, distribution and evolution in continental faulted basin. Through the core observation, field outcrop, logging curve identification and seismic data interpretation, Dainan Formation of Majiazui - Lianmenzhuang region in Subei Sag is divided into four sedimentary systems including lakes, sublacustrine fan, inshore subsea fan and fan delta. Based on the tectonic evolution of Majiazui -lianmengzhuang, this paper has concluded that the sedimentary system of Dainan Formation has apparent structural control behavior vertically and horizontally.
