摘　　要：根据岩心观察、测井资料以及区域地质背景等综合分析,对鄂尔多斯盆地南部富县地区延长组浊积沉积特征进行了讨论,认为富县地区浊积沉积主要发育在长6油层组和长7油层组,为三角洲前缘滑塌型,亚相分为外扇和中扇,内扇不发育。探讨了湖底滑塌浊积扇的成因机制,建立了相应的沉积模式,分析了其油气地质意义。According to the comprehensive analysis of core observation,logging data and regional geological backgroud,turbidite sedimentary characteristics of fuxian Area in southern Ordos Basin were discussed.It is considered that the turbidite deposition is mainly developed in Chang 6 and Chang 7 strata,the type of turbidite deposition is delta slump.It is divided into outer fan and middle fan,inner fan is not developed,the lake slump turbidite fan system is discussed.The corresponding depositional mode or pattern is established.Furthermore,its significance of oil and gas genesis is analyzed.
