A new technol. of share deposits by using perforating and fracturing tool was presented. At the design stage, a numerical model was constructed. Type and appropriate forms of propellant elements were selected. The process of reservoir rock fracturing by using the propellant rings was subjected to numerical anal. The model sections of perforating and fracturing tool were evaluated during the fire ground tests. The propellant rings operated effectively and intensified the oil and gas prodn.
