The hot fracturing fluid for oil well consists of glue forming agent, gluing agent, de-gluing agent and additive. The compounded solution system is heated to the designed temperature through the heating of hot steam, hot water or heat chemical reaction, and the density is increased to designed density. Compared with the available hot fracturing fluid, the present invention has similar sand carrying capacity, viscosity, friction resistance and filter loss; less residual content and damage to matrix, higher compounding property and energy accumulating modulus; and high temperature expansion preventing rate of about 10% and steam injecting pressure decrease of 5-10%. |
