FIELD: oil production. SUBSTANCE: invention is related to oil recovery and can be used to supply nitrogen-employing technologies while conducting drilling operations, coping with and running wells. Powder elements are ignited and burnt up in correspondence with proposed process. Pool is subjected to baric action thanks to usage of flashed-out gas. Sodium azide is employed in the capacity of powder elements. It is ignited and burnt up outside of well above well-head in device withstanding high pressure and temperature. Flashed-out gas is cleaned from mechanical impurities in filter, is cooled and is supplied into well over high-pressure pipe-line. EFFECT: safe and convenient running of wells. 1 cl, 1 dwg
