摘要
根据野外地质剖面以及测井相等标志，对吐哈盆地水西沟群沉积相进行了较全面、系统的研究，研究表明吐哈盆地主要发育扇三角洲相、辫状河三角洲相和湖泊相3种沉积相类型。扇三角洲以平原亚相和前缘亚相为主。辫状河三角洲相以辫状河三角洲前缘亚相为主，由水下分流河道、水下天然堤、支流间湾和河口砂坝微相组成；湖泊相以浅湖亚相为主要，由浅湖砂坝和浅湖泥组成。通过对每种沉积相、亚相和微相展布规律的研究，进而指出有利的沉积相带及其发育位置和平面展布特征，通过对沉积剖面和沉积相与油气关系的研究，指出有利于油气生成和储集的沉积相类型。
According to the field geological profile and signs of logging and other detailed studies to the Shuixigou Group of sedimentary facies in Tuha Basin more comprehensive and systematic research,the results indicate that Tuha Basin Tertiary syetem developed threee main sedimentary facies types :fan delta facies,braide river delta facies and lake facies.In the braide river delta,custom-shaped delta was grown.Subfacies is dominated by its underwater streaming river,underwater natural embankment,tributaries between Bay and the estuary sand Pa-in composition;shallow lake is the main type from shallow lakes and shallow lake mud and sand dam.Through each of the Sedimentary facies,subfacies and microfacies,it emphasized on the study of the exhibition.
