Abstract

Abstract

To optimize the techniques and operational parameters of well fracturing with supercritical CO2 fracturing fluid, a mathematical model coupling the pressure drawdown and heat transfer of a well fractured with CO₂ fracturing fluid is established based on the physical properties of CO₂, taking into account the mutual influence and interaction between the changes in temperature and pressure of the well and the properties of CO₂. The accuracy of the model is verified with data collected from field fracturing operations. Using this model, the effect of coupled temperature and pressure is calculated, and heat transfer pattern in the wellbore analyzed. Laboratory studies have shown that the temperature distribution inside the tubing is significantly lower than the in-situ formation temperature at different flow rates of the fracturing fluid. With the increase in flow rate, the wellbore temperature is first decreasing and then increasing. The bottomhole temperature is increasing with the increase in the temperature of the injected fluid, and the change in the bottomhole temperature becomes more significant with the temperature of the injected fluid at higher flow rates. Increase in the wellhead pressure has little, if any, influence on the bottomhole temperature, and its effect can be ignored in engineering calculations. The bottom hole temperature is always decreasing with time at different flow rates, and the amplitude of this temperature decrease is gradually decreasing with time. The tubing temperature can be significantly reduced if drag reducer is added into the fracturing fluid. At any flow rate, the changes in the wellbore temperatures are becoming smaller in a wellbore fractured with a fracturing fluid containing drag reducers. This research has important guiding significance to CO₂ fracturing design optimization and field operations.
