摘要: 剩余油研究是油田开发中后期油藏管理的主要任务,是实现"控水稳油"开发战略的重要手段。油田进入高含水后期开发后,随着开采程度加深,地下油水关系越来越复杂,非均质更严重,剩余油分布越来越复杂,给油田稳产和调整挖潜带来的难度越来越大。在结合项目研究成果及大量文献检索的基础上,阐述了我国剩余油研究的发展现状、主要技术及分布模式,归纳总结了剩余油的研究进展。Abstract: The study of remaining oil is a main task of reservoir management during the mid-late period of oil field development, is an important means of controlling water cut and stabilizing oil production as well.When oil field enters the developmental phase of high water cut, the relation of water and oil will be more complex, the reservoir heterogeneity will be more severity, the distribution of remaining oil will be more disperse, the difficulty of stabilizing oil production and adjusting measure will be bigger.The paper, ba sed on the authors' achievements in projects research and general review of a quantity of literatures, expatiated present situation, primary technology and the distributing modes of remaining oil, and summarized the recent advance of remaining oil.
