摘　　要：基于岩心长期注水试验资料 ,认识到吸水层的残余油饱和度的变化是一个缓慢减小的过程。文章给出了动态残余油饱和度的概念 ,提出了利用吸水剖面测井资料来确定动态残余油饱和度的方法。通过现场实测资料的解释 ,建立了动态残余油饱和度与吸水层每米累计吸水量的定量关系 ,为剩余油分布研究提供新思路。Based on core data of longtime waterflooding experiments, it is known that residual oil saturation of water intake layer is slowly decreasing. Concept of dynamic residual oil saturation is given. A method of determining dynamic residual oil saturation using log data of water intake profile is advanced. Quantitative relationship between the dynamic residual oil saturation and cumulative water intake capacity per meter is built through the interpretation of field data providing new thought for the study of remaining oil distribution.
