摘　　要：鄂尔多斯富县盒 1 段北物源砂岩储层低孔低渗,成岩作用复杂。通过分析成岩矿物与作用后将其划分为6种成岩相,在研究成岩成岩相类型与测井响不同特征基础上,用主成分分析法建立成岩相识别图版,结合试气成果建立两种主要成岩相测井识别标准。The sandstone reservoir in the northern provenance area of Member 1(He-1 Member)of the He Formation in Fuxian,Ordos Basin exhibits low porosity and low permeability characteristics with complex diagenetic evolution.Through analysis of diagenetic minerals and processes,six diagenetic facies were identified.Based on the distinct logging response characteristics of different diagenetic facies types,principal component analysis was employed to establish diagenetic facies identification charts.Furthermore,logging identification criteria for two predominant diagenetic facies were developed by integrating gas testing results.
