摘　　要：河南油田化学驱已形成油藏工程、驱油剂配方研发、地面工程设计等方面技术,在26个单元开展了化学驱工业化应用,油藏化学驱类型包括Ⅰ、Ⅱ类并探索了Ⅲ类油藏,技术方法涵盖了聚合物驱、复合驱、非均相驱等,化学驱已成为油田稳产或延缓产量递减的主体技术。随着优质资源的全面动用,目前面临着优质化学驱资源匮乏、化学驱项目效益下降、化学驱技术发展与创新的挑战。应对挑战的对策是做实基础工作,调整技术路线,强化技术攻关研究,深化注采工艺支撑和研发配套撬装化地面注聚系统,优选性价比高驱油剂,降低生产运行成本和地面投资,提升化学驱效果和效益,提高化学驱储量动用率,实现化学驱储量有序接替。The supporting technologies of chemical flooding such as reservoir engineering,flooding agent and surface engineering have been formed in Henan Oilfield.The industrial application has been carried out in 26 units and which include Class I and II reservoirs and develop towards ClassⅢreservoirs by chemical flooding.It experiences the application of polymer flooding,compound flooding and heterogeneous flooding,which becomes the main technologies for stabilizing production or delaying production decline.With the comprehensive utilization of high-quality resources,it is faced with the challenges of lack of highquality chemical flooding resources,the decline of chemical flooding project benefits,and the development and innovation of chemical flooding technology.Therefore,the countermeasures are to ensure the foundation,adjust the technology route,strengthen the technical research,deepen the injection-production process support,research and develop the matching skid-mounted surface polymer injection system,optimize the oil displacement agent with high cost performance,reduce the investment,promote the efficiency of chemical flooding,and improve the utilization rate of chemical flooding reserves,so as to achieve the orderly connection of chemical flooding reserves.
