FIELD: equipment for treatment of bottom-hole zones. SUBSTANCE: device includes implosive chambers, inlet valve, heating spiral, charge with ignition unit connected with surface control panel by means of electric wires. Internal space of inlet valve has cylindrical stop made of insulating thermoplastic material sewn with the first heating spiral connected with surface control panel. Change with ignition unit is located in fireproof protective case having side holes. Ignition unit consists of seal with the second heating spiral connected with surface control panel. Installed from outside, over circumference of implosive chamber, are adjoining to one another plates whose upper part is chamfered towards implosive chamber, and lower part is attached to implosive chamber body. Number of plates is 10-20. Plates may be two- layer. EFFECT: higher efficiency of removal of colmatage material from bottom-hole formation zone due to increased time of differential pressure, provided possibility for performance of work in wells with any angles of inclination and higher safety of labor conditions. 2 cl, 3 dwg
