An optimized high-energy gas fracturing technology was proposed to solve the difficulty on the stimulation of the deep tight gas reservoirs in the East China Sea. Temperature-resistant potassium perchlorate was preferred as the solid oxidant and temperature-resistant epoxy resin was used as the polymer binder. Addition with the use of high temperature-resistant rubber，sensitive agent，curing agent and other materials，the high temperature-resistant propellant was made by using a slurry casting process. The propellant could withstand a high temperature about 200 ℃ for 48 hours. According to the non-Darcy gas flow productivity formula and the multi-crack model after high-energy gas fracturing，the gas well productivity and production-increasing ratio model after the fracturing were derived. The correlation between the gas well productivity and fracturing parameters was analyzed. Fracturing mode with both built-in and sleeve-type propellant were optimized for different propellant parameters. The“TCP-HEGF-APR test”integration process technology has been formed innovatively. It greatly saves 50% working time，reduces reservoir damage and improves the safety of the downhole work with string tools.
