摘　　要：基于不同的泥浆侵入机理,在低渗透储层条件下,通过邻井油基泥浆取心分析资料与水基泥浆取心资料的对比,证实了低渗透储层水基泥浆取心含水饱和度能够作为储层原始含油饱和度,而在中高渗透性储层条件下,则提供了一种基于数理统计的饱和度校正方法,可以利用已有的水基泥浆取心饱和度资料较好估算油藏的原始含油饱和度。Based on different mud invasion mechanism and comparing methods between oil base mud coring analysis data with water base mud coring analysis data of adjacent wells in low permeability reservoir, it is proved that water base mud coring analysis data can be used to determine the origin oil saturation of reservoir in low permeability reservoir. For middle-high permeability reservoir, one saturation correction method which was based on mathematical statistics of those existed saturation data was put forward and was effect on estimation.
