Beschreibung
Zusammenfassung:	FIELD: well operation, for instance to operate oil, gas, water and other wells, particularly bottomhole formation zone treatment. ^ SUBSTANCE: method involves hydraulic cleaning of perforation zone of production well formation; applying high-power gas-impulsive action to bottomhole formation zone under pressure at shock front equal or exceeding mining pressure in treatment area; chemically treating bottomhole formation zone by pumping chemical reagent into treatment zone. ^ EFFECT: increased output from the well due to full permeability and porosity recovery. ^ 12 cl
