    Abstract
  • Sand carrying in CO2 fracturing fluid has been a problem because of the low viscosity of liquid CO2 which always results in poor fracturedevelopment in fractured formations. One of the key factors in the successful use of CO2 in reservoir fracturing is to increase the viscosity of CO2 used. According to the working mechanisms of Lewis acids and Lewis bases, an olein with Lewis base characteristics was chosen to mix with cyclohexane and chloroform in a ratio of (2.6-4.3) (1.0-2.3) (1.6-2.6) to form a liquid fluorine-free amphiphilic fatty compound, ZNJ, a viscosifier used to enhance the viscosity of CO2. At 20-25℃ and 18-20 MPa, liquid CO2 treated with 7% (vol.%) ZNJ had viscosity of 8.82 mPa·s, as measured on an MARS Ⅱ rheometer. At 10-20 MPa (controlled with a hand pump), 7-18℃, and shearing rate of 170 s-1, percent change in the viscosity of CO2 did not exceed 13%. The viscosifier has been used on 5 wells for 6 times. In the field applications, the concentration of ZNJ was 3%, the proppant used was haydite of 40-70 mesh, the maximum sand volume added in the fracturing fluid for a single fracturing zone was 10 m3, and the average ratio of sand to liquid was 6.1%. The fracturing job was smoothly performed, and the orientation of the fractures developed in the formations was in agreement with the orientation monitored in conventional fracturing jobs. It is concluded that liquid CO2 can be viscosified with olein, cyclohexane and chloroform.
