摘　　要：沉积相的研究对渭河盆地天然气勘探开发具有重要意义。通过构造背景、野外露头、岩性组合、沉积构造等资料的综合研究,分析总结渭河盆地张家坡组和蓝田灞河组沉积相,沉积相类型及沉积特征。结论表明,蓝田灞河组主要以洪积相,河流相,浅湖相为主;张家坡组主要以稳定的湖相沉积为主,经历了浅-深-浅湖的完整发展旋回。The study of sedimentary facies of the Wei- he basin natural gas exploration and development is important.Through the comprehensive study of constructing background,field outcrop,lithologic combination and sedimentary structure,it concluded sedimentary facies,sedimentary facies types and sedimentary characteristics of Zhang- jia- po group and the lantian- bahe group of the wei- he basin by the analysis summary. Conclusion shows that main sedimentary facies of the the lantian- bahe group are proluvial facies,fluvial facies and shallow lacustrine facies. The sedimentary facies of Zhangjiapo group is mainly stable lacustrine facies deposition. Zhangjiapo group experienced a full development cycle of shallow- deep- shallow lake.
