优势相分析在白家海—五彩湾地区苍房沟群沉积相分析中的应用
The application of the dominant sedimentary facies analysis to the Cangfanggou Group in the Baijiahai-Wucaiwan region,eastern Junggar Basin
【摘要】 在白家海—五彩湾地区苍房沟群沉积相分析中建立了优势相的划分标准,同时得出上苍房沟群的优势相为冲积扇—辫状河和曲流河,下苍房沟群的优势相为扇三角洲、滨浅湖和曲流河等。综合优势相分析和地震资料进行了沉积相的平面展布。
【Abstract】 The dominant sedimentary facies analysis is presented in this paper to the selection of the sedimentary facies that may represent specific sedimentary records.The dominant sedimentary facies consist separately of alluvial fan,braided stream and meandering stream facies in the Upper Cangfanggou Group,while the fan-delta,littoral and shallow lake,and meandering stream facies in the Lower Cangfanggou Group.The distribution of the above-mentioned dominant sedimentary facies is dealted with in detail on the basis of seismic data and criteria for the division of dominant sedimentary facies.
