摘　　要：油水饱和度是评价油层水淹情况、分析剩余油分布规律以及制定调整开发方案的重要依据。然而通过室内岩心分析获取油水饱和度资料与地层条件下存在偏差,需要校正后才能使用。目前,岩心油水饱和度校正方法主要有基于降压脱气实验校正法、基于相渗的分流量矫正法、基于数理统计的矫正法。Oil water saturation is an important basis for evaluating the flooding ofoil reservoirs, analyzing the law of remaining oil distribution and developing the adjustment and development plan. However, there is a deviation between the oil and water saturation data and the formation conditions through indoor core analysis, which need to be corrected before use. At present, the methods of correcting core oil saturation include correction method ofdegassing experiment based on depressurization, correction method of partial flow based on phase infiltration, and correction method based on mathematical statistics.
