FIELD: mining industry. SUBSTANCE: method includes connecting a well-washing apparatus to hole space and tubing string. Treatment periods include forming of depressive pressure overfall between well-adjacent layer area and well hollow by means of prior pumping of fluid into the well and creation of periodic pressure impulses in well-adjacent layer area in form of dumped stationary wave moving in hole space of well. Treatment periods are interchanged with well washing by means of said respective apparatus. EFFECT: combined well hollow and well-adjacent layer area cleaning. 2 dwg
