摘　　要：高含水期老油田二次开发既是油田开发历史上的一次革命,又是一场战略性的系统工程,对原油产量长期稳产发挥了不可替代的作用。从智能决策、智能规划、智能施工、智能监测、智能评估等方面,在碳达峰碳中和政策框架下,对中国老油田二次开发的前景进行展望。老油田二次开发须重构地下认识体系,重建井网结构,重组地面流程;技术上应整体控制、层系细分、平面重组、立体优化和深部调驱,做到二次开发与三次开发结合。The secondary development of mature oilfields with high water cut is a revolution in the history of oilfield development and also a strategic systematic project.It plays an irreplaceable role in maintaining long‑term stable oil production.From the aspects of intelligent decision‑making,intelligent planning,intelligent operation,intelligent monitoring,and intelligent evaluation,and within the framework of the policies for carbon peaking and carbon neutrality,the prospects for the secondary development of mature oilfields in China were discussed.It is indicated that the secondary development of mature fields should be implemented by reconstructing underground understanding system,well pattern,and surface process,and technically by way of overall control,stratigraphic subdivision,plane reorganization,three‑dimensional optimization,and deep profile control,ensuring the smooth integration of secondary development and tertiary development.
