  • This paper focuses on the Temperature-tolerance and Shear-resistance mechanism of a physical gel fracturing fluid, which is mainly divided into the following three aspects: (1)The microstructure of the solution is analyzed using a transmission electron microscope, and shear degradation phenomenon of the linear polymer (HPAM) and thickener (SMPT) is explained. (2)The influence factors of Temperature-tolerance and Shear-resistance of HPAM and SMPT are compared and analyzed through testing the viscoelastic modulus of samples before and after the Temperature-tolerance and Shear-resistance test. (3)The Factors of Temperature-tolerance and Shear-resistance Degradation of the physical gel was analyzed by the viscoelastic modulus and micromorphology of the samples before and after the Temperature-tolerance and Shear-resistance test of 0.6% HPAM + 0.5% PHCA and 0.6% SMPT + 0.5% PHCA. The result shows that sample of 0.6% HPAM + 0.5% PHCA undergoes shear degradation and transforms into a viscous fluid after the Temperature-tolerance and Shear-resistance test under the condition of 120 ℃, 170s-1 for 2 hours. Extraordinarily, the elastic factor retention rate of the physical gel (0.8% SMPT+0.5%PHCA) is 78.9% , indicating that the physical gel fracturing fluid can maintain strong elastic fluid characteristics undergo the Temperature-tolerance and shear-resistance test at 150℃. Activation energy data of Arrhenius equation η= A e(- Ea/RT) shows that PHCA can lower the activation energy and constraining the degradation of SMPT, which indicates that PHCA is able to enhance the structural stability of SMPT solution.
