中文摘要	柴达木盆地新生代时期气候较干燥,主要沉积棕色,浅灰色陆相碎屑岩.通过岩心观察,对路乐河组岩性,结构构造特征,暴露标志进行了分析,并结合测井曲线分析认为,本区路乐河组主要为一套发育于干旱半干旱环境的末端扇沉积体系,可进一步划分为主流带,分流带和远端盆地带3个亚相,其中分流带亚相又可划分为分流河道沉积,泛滥平原沉积,越岸沉积和漫流沉积等4个微相.文中分析了各亚相平面展布特征,建立了沉积相模式.通过分析各亚相砂体的特征及其与储层发育的关系,认为分流带亚相是最有利的储层发育相带
英文摘要	The climate of the Qaidam Basin was arid to semiarid at the Cenozoic, and the strata deposits mainly are terrigenous clastics. Based on the core observation, the lithology, rock texture, sedimentary structure and the exposure evidence of Lulehe Formation are analyzed. Combined with well log analyses, it is believed that the sedimentary system of Lulehe Formation is terminal fan which formed in arid to semiarid regions. The model includes a tripartite zonation of terminal fan into feeder zone, distributary zone and basinal zone. The distributary zone mainly consists of distributary channel deposit, flood plain deposit, overbank deposit and sheet flood deposit. Feeder and distributary zone are the main deposition in Qianxi area. The subfacies distribution is analyzed and the sedimentary facies model is established. The relationship between subfacies and reservoir development is discussed and the distributary zone is the most favorable subfacies for reservoir development
