摘　　要：介绍了欢50块油藏CO2驱的室内实验情况,综合考虑油藏特性、储层特性、原油性质和转驱时机等,建立了二氧化碳驱油藏筛选原则和筛选条件;通过室内物模实验,对欢50块进行盖层密封性、断层密闭性、储层适应性和流体适应性研究,认为欢50块适合CO2驱,可实施注CO2开发。Laboratory test of reservoir CO2 flooding of Huan 50 block has been introduced in this paper. By comprehensively considering oil reservoir characteristics, reservoir characteristics and crude oil properties, the principles and conditions of reservoir CO2 flooding screening have been established. Through the indoor physical model test, the cover sealing, fault impermeability, reservoir adaptability and fluid adaptability research have been carried out. The results indicate CO2 flooding is fit for Huan 50 block and the CO2 development can be implemented.
