A new approach to viscosity enhancement of oils and CO2

Due to the naturally low viscosity of liquid CO2 (0.1-1.0 cP pressure/temperature dependent) the CO2 is prone to ¿fingering¿, limiting the efficiency of CO2-EOR [1]. In order to...由于液态二氧化碳（liquid CO2）固有黏度较低（范围为0.1~1.0厘泊（cP），且随压力与温度变化），其极易发生粘性指进（fingering）现象，进而限制了二氧化碳强化采油（CO2-EOR，Carbon Dioxide Enhanced Oil Recovery）的效率[1]。为了……
