Beschreibung
Zusammenfassung:	FIELD: oil industry. SUBSTANCE: given process can find use in treatment of face zone of wells. Extent of interval of treatment is fixed according to invention relative to face of well. Reagent is pumped under pulsating mode: pumping under pressure of intake of reagent by perforation interval - technological holding under atmospheric pressure. This mode is repeated under reduced pressure of pumping of reagent till pressure of operational pickup of well is achieved. Remaining volume of regent is pumped under steady pressure. Technological holding is conducted and reaction products and pollutants are recovered by swabbing prior to extraction of fluid in volume exceeding that of pumped reagent by factor of three as minimum. EFFECT: enhanced efficiency of treatment.
