Abstract: High energy gas fracturing has been developed from single fracturing technique of cased charge, uncased charge, liquid powder, controlled pulse to integrated fracturing technique cooperated with perforation, hydraulic fracturing, acidizing and other chemical treatments interiorly. This paper presented the basic principle, field test, treatment result of high energy gas fracturing cooperated with perforation, hydraulic fracturing, acidizing and other chemical treatments. The technique of high energy gas fracturing has been advanced to a new, normal mature, integrated technique for reservoir stimulation.
