The temperature resistance and shear resistance of fracturing fluid, as well as its sand-carrying capacity, directly influence its capacity to create fractures and carry sand. Temperature resistance and shear resistance are also referred to as viscosity. Through laboratory experiments, the temperature resistance and shear resistance of fracturing fluid at different temperatures, as well as the sand-carrying capacity of fracturing fluid at varying temperatures and sand ratios, were tested. The experimental results revealed that the fracturing fluid system exhibited excellent temperature resistance and shear resistance. Even after being sheared for 30 min at elevated temperatures, the viscosity could still be maintained at approximately 150 mPa s, fully meeting the requirements of fracturing construction. At the same temperature, the settling rate of proppants was observed to decrease gradually with increasing sand ratio. For example, at 45 °C, as the sand ratio was increased from 10 to 60%, the settling rate of proppants was observed to decrease from 0.03114 to 0.02085 cm/min, thereby facilitating the smooth implementation of temporary plugging fracturing construction. Additionally, with an increase in the depth of the construction layer, the temperature was also observed to rise accordingly. For a sand-carrying ratio of 30%, as the formation temperature was increased from 30 to 90 °C, the settling rate of proppants was observed to increase from 0.00446 to 0.15600 cm/min. It is recommended to adjust the sand-carrying ratio of fracturing fluid appropriately for different temperature construction layers to enhance sand-carrying capacity, ensuring the success of fracturing construction in high-temperature layers.
