摘　　要：针对南海西部油田普遍存在的生产井目前油层剩余油饱和度和含水率不清楚的问题,本文通过对其饱和度测井资料进行解释评价,并基于研究区块实验资料定量评价了水淹特征参数,进而实现了水淹级别的划分,为有效评价油田开发潜力和实行挖潜措施提供了保障。在此基础上进一步通过井间平面对比研究了剩余油分布规律,为提高采收率,进一步完善井网和调整井的井位分布提供有力依据。In allusion to the ubiquitous problem of the present vague residual oil saturation and water cut of oil reservoir in the west of South China Sea,the study explained the saturation logging data and quantificationally evaluated the parameters of water flooded character based on the experimental informations,which realized the partition of flooded level and provided guarantee of availably evaluation of exploiture potential of the oil field and potential excavation. On this foundation,the study of residual oil distributing rule through complanate contrast among wells provided convincing gist for recovery ratio enhancement,consummation of well pattern and the distributing of location of adjustment wells.
