摘　　要：对曲堤油田测井、录井、岩心分析等资料的研究分析表明,岩性细、孔隙结构复杂,造成储层的微孔隙发育,进而导致束缚水饱和度极高是该油田形成低阻油层的主要成因。在分析电测曲线形态的基础上,提出了利用饱满系数(RAD)、椭圆度(RAT)等曲线形态量化参数自动识别低阻油层的方法,取得了令人满意的应用效果。Study on well logging and core analysis shows that fine lithology and complicate pore structure are main reason for micropores development of reservoirs,causing ultra-high irreducible water saturation.Based on analysis on electric logging curve,it is proposed to identify low-resistivity layer with curve-quantified parameters,such as RAD and RAT,and this method has satisfied effect.
