摘　　要：依据陆相层序地层学原理及野外露头层序地层学方法,对楚雄盆地东山-黑井凹陷的上寒武统—下古新统进行了系统的层序地层学研究。共识别出11个三级层序界面(其中I型4个,II型7个),界面类型包括海侵上超面、水下间断面、陆上暴露面、升隆侵蚀面及造山升隆侵蚀面等5种形式,从而将研究区划分为12个三级层序。通过层序框架下的体系域组成及可能存在的有利储集相带综合研究分析,提出了分别在低位域、海侵域和高位域控制下的有利储集层相带及展布范围。The upper Cambrian-lower Paleocene in Dongshan-Heijing Sag of Chuxiong Basin is systematically studied according to the principles of continental sequence stratigraphy and outcrop sequence.Totally 11 sequence boundaries of Class-III (including 4 of Type I,7 of Type II) have been recognized,including five forms such as transgression onlap,subaqueous hiatus,subaerial exposure,heaving erosion and orogenic uplift erosion,thus dividing the study area into 12 sequences of Class-III.Integrated study and analysis of the system tracts and possible reservoir facies belts within the sequence framework have presented favorable reservoir facies belts and distribution ranges respectively controlled by lowstand system tract,transgression system tract and highstand system tract.
