摘要
该文分析了临清坳陷晚古生代沉积体系及沉积相,通过连井剖面沉积相的对比研究总结出其纵向演化特征。研究结果表明:临清坳陷晚古生代主要发育了台地-泻湖沉积体系、障壁-泻湖-潮坪沉积体系、潮坪沉积体系、河控浅水三角洲沉积体系以及河流-湖泊复合沉积体系。研究区沉积演化在纵向上表现清晰,其中晚石炭世—早二叠世的本溪、太原期主要发育海相沉积;二叠纪山西期主要为过渡相沉积;二叠纪上、下石盒子期主要为陆相沉积。
In this paper,sedimentary system and facies of Linqing depression have been analyzed.Through contrast and study on sedimentary facies of connecting wells,its vertical evolution characteristics have been summarized.It is showed that the platform-lagoon sedimentary system,barrier-lagoon-tidal flat sedimentary system,tidal flat sedimentary system,fluvial-controlled shallow-water deltaic sedimentary system and river-lake sedimentary system are mainly developed in the late Paleozoic in Linqing depression.The evolution of sedimentary facies in vertical direction is very clear.Marine environment sedimentary is mainly developed in Benxi and Taiyuan period in late Carboniferous and early Permian period;transitional facies environment sedimentary is mainly developed in Permian Shanxi period;and terrestrial environment sedimentary is mainly developed in Permian Shihezi period.
