The prominent characteristics of TOC high-energy gas fracturing technology with rocket propellant as fuel are its controllable combustion rate, longer pressurization time and longer and wider fracture length compared with other high energy gas fracturing technologies.

Well and layer selection criteria of liquid propellant high energy gas fracturing (HEGF) are included in this paper.

On the basis of investigating foreign information and according to the characteristics in high engery gas fracturing process on different formation conditions where high velocity, high temperature and high pressure pulses react instaneously and dynamically, a testing system on downho1e pressure vs time process was developed.
