【摘要】 通过钻井、测井、地震等资料的分析,采用沉积学、地层学、古生物学、地球化学、岩石学等多学科综合的方法,对济阳探区中生界沉积特征、相及沉积体系进行了较为全面、系统的研究。研究表明,济阳坳陷中生代主要发育六种沉积相类型及相组合,即冲积扇相组合、河流相组合、三角洲体系及相组合、滨浅湖相、湖湾相、沼泽相。济阳坳陷中生代坊子组时期以滨浅湖沉积为主;三台组主要发育冲积平原亚相。更多还原

【Abstract】 Based on the analyzing the data of the well,logging,seismic,sedimentary characteristics,facies and depositional system of the exploration area in Mesozoic of Jiyang Depression.are studied in detailed by the way of sedimentology,stratigraphy,paleontology,geochemistry,petrology and multidisciplinary integrated method. The results show that Jiyang Depression mainly developed six types of sedimentary facies and facies group,namely alluvial fan facies group,fluvial facies group,delta system and facies group,shallow lake facies,arm of lake facies and swamp. During the period of Fangzi Formation,there is mainly shallow-lake sediment; During the period of Santai Formation,it mainly developed alluvial plain subfacies; During the period of Mengyin Formation it principal developed littoral and shallow lake subfacies and alluvial plain subfacies. And fan delta facies was more than the one of the period of Santai Formation.更多还原
