| Abstract: | 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%. |
