摘　　要：我国致密油藏地质勘探资源储量高,储层条件差。常规注水开发无法满足致密油藏目前的开发需求。CO_(2)驱油技术在致密油藏的开发中具有一定的应用潜力,但其驱油过程面临技术、经济等方面的制约。本文总结了CO_(2)驱油技术研究及应用现状,并从多角度对CO_(2)驱油技术的影响因素进行分析,旨在为CO_(2)驱油技术在致密油藏开采过程中的低能耗高产出提供指导。The geological exploration resources of tight oil reservoirs in China have high reserves and poor reservoir conditions.It is no longer enough to meet the current development needs of tight reservoirs by conventional water injection development.CO_(2)enhanced oil recovery(EOR)technology has certain application potential in the development of tight oil reservoirs,but its oil recovery process is constrained by technical and economic factors.This article summarizes the research and current application status of CO_(2)-EOR technology in tight oil reservoirs and analyzes the influencing factors of CO_(2)-EOR technology from multiple perspectives.It aims to provide guidance for low energy consumption and high production output of CO_(2)-EOR technology in the exploitation process of tight oil reservoirs.
