    Abstract
  • In reservoir fracturing with liquid CO2 (LCO2), low viscosity of the fracturing fluid has long been a problem restricting the spread of this new fracturing technology.The phase change of LCO2 after mixing it with a thickening agent LPE and a micelle enhancer CJ-1 has been studied to investigate the thickening mechanisms of LCO2 -LPE-CJ-1. HAAKE viscotesters (Model D300/D400) were used to verify the thickening effect of LPE+CJ-1 on the LCO2. Using polarizing microscope, the state of the micelles of the LCO2 -LPE-CJ-1 fracturing fluid was studied. The experimental results showed that LPE and CJ-1 can thicken the LCO2 -LPE-CJ-1 fracturing fluid to about 112 mPa·s, nearly 6 times of the highest viscosity of LCO2 (20 mPa·s)that had been reported previously. The thickening mechanismsare that,through ionic complexation between the molecules of LPE and CJ-1, the two molecules form rod-shaped micelles, a structure analogous to the 3-D spatial network structure formed by the intertwined molecules of a crosslinked polymer.
