摘　　要：苏里格气田南区二叠系山1二叠系盒8气储层的综合分析研究表明,鄂尔多斯二叠系山1期为曲流河三角洲沉积,以三角洲前缘亚相沉积最为发育,主要发育水下分流河道和水下分流间湾微相等微相,水下分流河道砂体是天然气储集的骨架砂体。二叠系山1和二叠系盒8气储层沉积相存在差异,但曲线形态基本相同,砂岩的电测曲线特征为箱状、钟状,自然伽玛曲线幅度较低,齿化较少,二叠系山1气储层在电性上表现为低伽玛、低密度、高时差特点(储层好);二叠系盒8段储层整体表现为一套低伽玛、高电阻的电性特征。Gas fields in China land is the largest ready natural gas,natural gas resource of 3.8 trillion cubic meters,but gas surface in a complex geological situation,different thickness of gas layers,most of the store in sandstone gas reservoir,gas field development is very difficult,in this paper,combining with working practice,this paper discusses the gas mainly in formation characteristics and well logging curve in the formation of response law and how to accurately stratified.
