摘　　要：苏北盆地金湖凹陷MQ地区古近系阜宁组三段(E1f3)低阻油层含油饱和度主要受岩性、物性及测井因素影响。针对常规阿尔奇公式计算的含油饱和度明显偏低现象,主要采用毛细管压力曲线法、相对渗透率曲线法和测井资料优化解释法确定低阻油层的含油饱和度,有效避免了引起低阻的因素的影响,从而提高了含油饱和度的计算精度。In MQ area,oil saturation in low resistivity reservoirs of the 3rd member of Funing Formation of Palaeagane System(E1f3)was mainly affected by the lithology,physical property and logging factors.In allusion to the issue of lower oil saturation calculated by conventional Archie equation,the capillary pressure curve method,relative permeability curve method and logging data optimization method are used to determine the oil saturation in low resistivity reservoirs,it effectively avoid the factors causing low resistance factors,thereby the accuracy of the calculation of the oil saturation is improved.
