摘　　要：在系统分析内蒙古金宝屯盆地协尔苏组钻孔岩心、测井、古生物等资料的基础上,对金宝屯盆地的煤与油页岩共生发育的沉积环境、层序地层特征等进行深入研究。研究发现,协尔苏组存在两种煤与油页岩共生组合类型(自上而下):煤层-油页岩(C-OS)组合和煤层-油页岩-煤层(C-OS-C)组合,主要发育于深湖-半深湖向三角洲过渡的环境,煤与油页岩共生组合仅发育在盆地演化晚期的高水位体系域。构造运动、基底地形、水体深度与分层等因素综合控制了煤、油页岩的发育与展布,进而控制了煤与油页岩共生组合发育的类型、演化及展布特征。Based on the systematical ananlysis of drill core, logging and paleontology data ofXieersu Formation in Jinbaotun basin in Inner Mongolia, a further study was conducted on thesedimentary environment o{ coal and oil shale symbiotic development and sequence stratigraphycharacteristics. According to the research, there are two types of coal and oil shale symbioticcombination （from top to bottom）, coal-oil shale （C-OS） and coal-oil shale-coal （C-OS-C）,mainly developed in the environment that transited from deep lake-half deep lake to the delta, andthe coal and oil shale symbiotic combination just developed in late highstand system tract. Somefactors such as tectonic movement, basement terrain, water depth and hierarchy controlled thedevelopment and distribution of the coal and oil shale, and further controlled the type, evolutionand distribution characteristics of the coal and oil shale symbiotic combination.
