摘　　要：CO2驱采出水中成垢离子浓度随采出时间的增长不断增加,采出井中温度、流速、CO2分压层梯度变化,导致结垢趋势增加。通过模拟现场环境,利用改进后的静态法结合表面分析手段,研制出高效复合性阻垢剂并研究了其性能,阻垢效率可达到99.14%。The concentrations of the precipitating ions in the produced water of CO2 flooding increased with the time. The temperature, fluid state and divider layer of carbon dioxide with gradient diversification enhanced the scaling trends. The compound scale inhibitor with high efficiency was investigated in the simulated site environment. The improved static methods and surface analysis were employed to get knowledge of the properties of the inhibitor. The scaling inhibition rate is 99.14%.
