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。
沉積相的研究對渭河盆地天然氣勘探開髮具有重要意義。通過構造揹景、野外露頭、巖性組閤、沉積構造等資料的綜閤研究，分析總結渭河盆地張傢坡組和藍田灞河組沉積相，沉積相類型及沉積特徵。結論錶明，藍田灞河組主要以洪積相，河流相，淺湖相為主；張傢坡組主要以穩定的湖相沉積為主，經歷瞭淺-深-淺湖的完整髮展鏇迴。

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 lan-tian-bahe group of the wei-he basin by the analysis summary. Conclusion shows that main sedimentary facies of the the lan-tian-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.
