Abstract: FIELD: oil production industry. SUBSTANCE: this relates to treating oil bed by pressure of explosive powder gases. According to method, being burnt in interval of productive bed is powder charge made of solid-fuel material with filler-stabilizer of burning. Accumulation of powder gas pressure is effected in space of central round passage. Length and diameter of this passage are related as 20-40:1 with content of filler-stabilizer of burning to total mass of central round passage being not over 1.5%. In space of central passage in which length and diameter are related as 40-120:1, content of filler-stabilizer is not over 0.6%. Powder gas pressure is transmitted from central passage space to oil bed in the form of pressure pulses through radial passages and side surfaces. In result of burning, created in central round passage are thermo-gas-chemical, baric, vibro-wave processes with simultaneous alternate electric current effect. This guarantees high intensity of treating productive oil bed to any depth and at any bed conditions. EFFECT: high efficiency.
