摘　　要：以鄂尔多斯盆地瓦窑堡油区长2^(1)段储层为主要研究对象,结合野外剖面和沉积特征、测井曲线特征对其沉积相特征和砂体展布规律进行了深入的分析与探讨。结果表明:研究区长21段储层主要以曲流河沉积为主,发育两种沉积亚相,四种沉积微相,且沉积相带对砂体的展布规律具有很好的相控作用,这为后期储层评价以及勘探开发工作的开展提供了地质依据。Taking the chang 2^(1)member reservoir in Wayaopu oilfield of Ordos Basin as the main research object,this paper deeply analyzes and discusses the sedimentary facies characteristics and sand body distribution law combined with the field profile,sedimentary characteristics and logging characteristics.The results show that the reservoir of Chang 2 member in the study area is mainly composed of meandering river deposits,with two kinds of sedimentary subfacies and four kinds of sedimentary microfacies.Moreover,the sedimentary facies belt has a good controlling effect on the distribution law of sandstone,which provides geological basis for reservoir evaluation in later exploration and development.
