通过对研究区露头、岩性、测井等特征的研究，将柴达木盆地新近纪上下油砂山组划分出5种重要的沉积相类型：冲积扇相、河流相、扇三角洲相、三角洲相、湖泊相，并进行详细描述。依据单因素分析多因素综合画图的方法论，做出上下油砂山组沉积相平面展布图。沉积相带是控制储层特征和分布的基本因素。结合沉积相带图，划出油砂山组储集相带，有利储集相主要是三角州前缘砂体，冲积扇-扇三角洲分流河道砂体，浅湖滩坝；主要分布在沙西、乌南、咸水泉、月牙山、红沟子、阿尔金斜坡带，而碱山地区的储集相带发育较差。
通過對研究區露頭、巖性、測井等特徵的研究，將柴達木盆地新近紀上下油砂山組劃分齣5種重要的沉積相類型：遲積扇相、河流相、扇三角洲相、三角洲相、湖泊相，併進行詳細描述。依據單因素分析多因素綜閤畫圖的方法論，做齣上下油砂山組沉積相平麵展佈圖。沉積相帶是控製儲層特徵和分佈的基本因素。結閤沉積相帶圖，劃齣油砂山組儲集相帶，有利儲集相主要是三角州前緣砂體，遲積扇-扇三角洲分流河道砂體，淺湖灘壩；主要分佈在沙西、烏南、鹹水泉、月牙山、紅溝子、阿爾金斜坡帶，而堿山地區的儲集相帶髮育較差。

Through study on outcrops,lithology,logging features in the studying area,upper and lower parts of Ne-ogene Youshashan formtion in Chaidamu basin have been divided into five important types of sedimentary facies,in-cluding alluvial fan facies,fluvial facies,fan delta facies,delta facies and lacustrine facies,and have been de-scribed in detail.By using multi factor comprehensive mapping method based on single factor,plane distribution map of sedimentary facies of Youshashan formation has been made.Sedimentary facies zone is the basic factor for controlling reservoir distribution and characteristics.Combining with sedimentary facies belt graph,reservoir facies belt in Youshanshan formtion have been circled.Favorable reservoir facies are mainly composed of delta front sand-stone,alluvial fan fan delta distributary sandstone,channel shallow lake beach and daml.They mainly distributed in Shaxi,Wunan,Xianshuiquan,Yueyashan,Honggouzi and Aerjin slope belts.While reservoir facies poorly de-veloped in Jianshan area.
