摘　　要：北80井区三叠系下统油层具有明显的低电阻率油层的特征,通过研究认为储层粘土矿物含量高、孔隙结构较差、束缚水含量高、高矿化度地层水以及储层内易导电的特殊重矿物含量高是形成低电阻率油层的主要原因,可动水分析法评价法是该区较为有效的识别油气层的方法。The reservoir of bottom Triassic system in Bei 80 well field has obvious low-resistive formation feature,we think high clay mineral of the resistive ;bad pore configuration ;high bound water ;high-salinity formation water and the conducting particular heavy crop in reservoir are the low-resistive formation factors by research.evaluation by the analyses of the movable water is an effective method to identify the hydrocarbon reservoir in this area.
