摘　　要：目前，国内外确定剩余油饱和度及其分布技术归纳起来可分为四类：单井分析技术、井间测试技术、室内模拟技术和油藏动态分析技术。每种技术都有其优点和局限，在实际应用中通常采用多种技术的综合。相对稀油而言，稠油剩余油饱和度及其分布的研究起步较晚。辽河油田稠油的多数主力区块都进入吞吐开采中后期，通过油蒇精细描述，应用测井、室内模拟和油藏动态分析等技术研究稠油剩余油的分布，对油田的长期高产稳产起着十分关键的作用。In mid-late period of oil field development,determination of remaining oil saturation and its distribution is rather important for slection of process measures,modification of development scheme and improvement of ultimate recovery factor. At present, technologies of determining remaining oil saturation and its distribution at home and abroad can be divided into four types:single well analysis technology, interwell testingtechnology, indoor modeling technology and reservoir dynamic analysis technology. Each of these technologies has its advantage and disadvantage. Comprehensive utilization of these technologies is usually adopted inpractice. Study of remaining oil saturation and distribution of heavy oil is later than that of light oil. China isrich in heavy oil resources,especially in Liaohe oil field,and most main blocks of heavy oil are in mid -laterperiod of huff and puff phase. Study of remaining oil distribution of heavy oil based on accurate reservoir description through well .logging,indoor modeling and reservoir dynamic analysis technologies is very importantfor long term of high and stable production.
