摘要：In this study, According to the requirement of high temperature low permeability reservoir hydraulic fracturing fluid. A novel non-residual fracturing fluid was developed through analyzing the structure of polymer 2-acrylamido-2-methylpropanesulfonic acid(AMPS). Experiment results demonstrate that synthetic polymer fracturing fluid possess good shear stability and viscosity recovery propriety. The shear viscosity of fracturing fluid for 120min is 120mPa.s in 170 °C, it has good resistance to high temperature and shearing performance. The residue of polymer fracturing fluid was 1.2%. Matrix and propped fracture damage test indicate that the damage to core matrix(only 15.4%) and propped fracture of synthetic polymer fracturing fluid is far less than guar gum fracturing fluid which is fit for the stimulation of high-temperature low permeability reservoir. The new fluid was tested in 120 wells in the gas and oil reservoir in China. Oil &gas production after stimulation using the new fluid increased 3to 5 times compared with wells in similar locations.
