Abstract: In order to meet the demand of the fracturing fluid used in Anpeng Oilfield which is low porosity, poor permeability, high temperature and plentiful fracture reservoir, experiment temperature for assessing fracturing fluid has been determined. Thickener, gellant, viscosity breaker and cleanup additive have been selected optimally. The fracturing fluid system has been formulated which is suitable for the zones of Anpeng Oilfield. The fracturing fluid has the advantages of high temperature resistance, shear resistance, delayed crosslinking, excellent prop-carrying capacity, complete viscosity breaking and low damage. The fracturing fluid can be used in the zones whose temperature is between 90℃ and 140℃. The fracturing fluid has been used in 49 wells for fracturing operation. Success ratio is 91.3%. The problem of sand plugging for high temperature fracture reservoir has been solved.

Key words: fracture reservoir, hydraulic fracturing, fracturing fluid, additives
