A novel supramolecular nano composite clean fracturing fluid system consisting of a new type of surfactant(VES-M) and polyacrylamide copolymer(HMPAM) and nanoparticles(ZnO) were investigated, with the characteristics of low using concentration of surfactant and less type of additive. Laboratory test showed that, compared with regular cleaning viscoelastic surfactant fracturing liquid, nano composite clean fracturing fluid system has higher heat resistance and shear resistance performance, enhanced fluid loss prevention, better viscoelastic and sand carrying ability, and gel breaking thoroughly and rapidly, without residues after broken, core damage rate is only 9.3%. Application was carried out successfully in the east area of Sulige gas field in 2014, the mean gas open-flow capacity of test wells is about 2.0 times that of the same geological conditions of adjacent wells, which provides an effective way of low damage efficient stimulation for tight gas reservoir.
