description FIELD: oil and gas industry. ^ SUBSTANCE: invention relates to the oil industry and can be used in affecting the bottomhole well zone for productivity improvement. The method includes impacting the bottomhole with the falling weight with simultaneous injecting liquid into the well and lifting the plunger by hydraulic energy of the liquid flow injected into the well; after the each weight knock, the additional knock at the bottomhole is made by falling plunger via load; the bottomhole zone is treated by hydraulic pressure pulsations simultaneously with knocking, and the chemical reagents are injected into the bottomhole zone. The invention is developed in dependent points. ^ EFFECT: efficiency of affecting well bottomhole zone is increased. ^ 5 cl, 3 dwg
