摘　　要：滨南—利津断裂带发现较大规模低电阻率油藏,结合低阻油层的成因分析该地区储层电阻率的高低不仅与储层的含水饱和度有关,还与储层的孔隙度、岩性及岩性粗细密切相关。为避免传统的依据邻井的试产结果进行识别评价的方法,选用三孔隙度曲线重叠方法判别低阻油层,提出利用中子、密度和声波测井信息计算岩矿成分和粒径指数进行低阻油层的定量评价方法,并应用于测井评价,效果良好。A large low resistivity reservoir has been found in the fault zone of Binnan-Lijin.According to the causes analysis to low resistivity reservoir,the resistivity reservoir in this region is related to not only the reservoir water saturation,but also the reservoir porosity,lithology and the thickness of lithology.To avoid the conventional identification and evaluation method that based on the results of trial production of adjacent wells,we select three porosity curves overlapping method to discriminate low resistivity reservoir,and propose a method by using neutron,density and sonic logging information to calculate rock ore compositions and particle size index to quantitatively evaluate to low resistivity reservoir.Then it is applied to logging evaluation and with good effects.
