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。
Currently, the determination of residual oil saturation and its distribution technology at home and abroad can be summarized into four categories: single well analysis technology, well testing technology, indoor simulation technology and reservoir dynamic analysis technology. Each technology has its advantages and limitations, usually in a practical application of a variety of technologies. Relatively thin oil, heavy oil residual oil saturation and its distribution started late. Most of the major blocks of heavy oil in Liaohe Oilfield have entered the middle and late stages of the huff and puff, and the distribution of the remaining oil in heavy oil has been studied through the fine description of oil shale, application of logging, indoor simulation and dynamic analysis of reservoir. The long- A very crucial role.
