FIELD: oil and gas industry.
SUBSTANCE: invention elates to oil products extraction, particularly to methods of impact to pay area for restoration of wells oil recovery. It is provided range of application expansion of method and its effectiveness increase. Essence of invention: method includes delivery into the pay space and burning in it of pyrotechnical charge, creation of depression and following removal from the pay space of downhole liquid with arrived in it from the layer bottomhole - LB mud elements. According to the invention beforehand in well in filter zone of LB it is implemented additional spared perforation with density not more than 3 holes per metre. Then it is pumped into the LB hydrophobic solution in amount, providing the formation of watertight hydrophobic screen, cut off water-saturated beds in the near pay area. Additionally creation of depression and following removal of formation water with arrived in it mud elements is implemented by means of well-swabbing up to installed as constant oil product inflow with simultaneous regulation of mud elements arriving on the surface.
EFFECT: range of application expansion and its effectiveness increase.
