| 摘 要： | 为了明确鄂尔多斯盆地东南部长7油层组沉积体系类型和沉积相展布特征，总结其沉积演化规律，以沉积学的基本原理和方法为指导，综合运用地球化学、盆地分析等理论和方法，通过野外露头、钻井、测井等资料的综合分析，认为鄂尔多斯盆地东南部长7油层组主要发育三角洲和湖泊沉积体系，可进一步划分为3类亚相，其中以三角洲前缘和深湖2种亚相为主．

| Abstract: | To clear the sedimentary system types and sedimentary facies distribution characters of Chang 7 oil formation of triassic Yanchang formation in Ordos basin,this paper conclude sedimentary evolution rules and analysis the principal controls of accumulation and resources potential.Using fundamental and methods of sedimentology,theories and methods of geochemistry and basin analysis,combining with outcrops,drilling and logging data,this paper consider that Chang 7 oil formation mainly develop delta and lake depositional systems.They are further sub-divided into 3 subfacies,in which delta front and deep lake facies are majority. |
