Abstract: In view of the fact that there are some limitations when remaining oil saturation is determined by using resistivity log or nuclear log during the water drive period of a pool,the theory and method that remaining oil saturation of producing interval is estimated from Production Logging Data are presented and described systematically.A practical method is investigated by the relationship between remaining oil saturation and water cut established from combining data of relative permeability of core analyses with those of production performances of oil field.Field examples analyses demonstrate that the method has some advantages over conventional well logging methods,which include less influence of salinity of formation water,larger scope of investigation and better practicality.The method is more applicable to performance monitoring of remaining oil distribution in productive interval of water drive pool.

Key words: production logging, remaining oil saturation, water-drive, reservoir, water cut

摘要： 利用常规电阻率测井资料和放射性测井资料确定油田注水开发期剩余油饱和度都有一定的局限性.本文提出并较系统地阐述了利用生产测井资料确定产层剩余油饱和度的理论和方法,同时提出一种利用岩心分析的油水相对渗透率和生产动态资料确定剩余油饱和度的产水率解释模型的实用方法.油田实例分析表明,与其它确定剩余油饱和度测井方法相比较,该方法具有不受地层水矿化度影响、结果代表范围大、实用性强等特点,更适合于确定水驱油藏产层剩余油分布及对其进行动态监测.
