摘　　要：以鄂尔多斯盆地大牛地气田大17未开发井区下石盒子组盒1段为研究对象,通过对区内重点钻井岩心观察,并结合测井资料分析,对盒1段沉积微相类型、特征及平面分布进行了深入研究。结果表明:大17井区下石盒子组盒1段为辫状河沉积,并可进一步识别出高能心滩、低能心滩、泛滥平原微相。在上述基础上,开展了沉积微相横向对比及垂向演化研究;进而,在各小层沉积微相平面图编制的基础上,详细描述了不同时期河道及泛滥平原的展布特征。研究成果为未开发区进一步开发提供了重要的基础资料。By taking He 1 Member of 17 Well Area of Daniudi gas field in Ordos basin as the research object,through key drilling core observation through the area,and combining with the logging data analysis,He 1 Member of the types,characteristics and plane distribution of sedimentary microfacies are carried on the in-depth research.The results showed that He 1 Member of Xiashihezi Formation is classified into braided river sedimentary facies and3 sedimentary microfacies,such as high-energy channel bar,low-energy channel bar and riverbed runway resort.On the basis of the above,carried out research of sedimengtary microfacies horizontal comparison and vertical evolution; then describes in detail different period distribution characteristics of river channel and riverbed runway resort on the plan views of sedimentary microfacies plan compiling in the small layers. Research results obtained for the further development of undeveloped region provides important basic data.
