摘　　要：在总结复杂小断块油田CO2吞吐系列配套技术的基础上,分别从油藏规模、物性、能量等角度剖析了71口吞吐井的实施效果,分析了影响CO2吞吐效果的关键参数,得出了注入量、注入压力、返排速度、吞吐周期等工艺技术参数的取值范围和标准,对提高采收率具有重要意义。This paper summarizes the technologies of CO_2 stimulation in small complex faulted block oilfields, studies the responses of 71 stimulation wells in aspects of reservoir scale, petrophysical property and energy, analyzes the key factors affecting CO_2 stimulation, gives the range and standard of process parameters like injection rate, injection pressure, backflow rate and cycle period. These are of significance meaning to improving recovery factor.
