Zusammenfassung:	FIELD: oil extractive industry. ^ SUBSTANCE: device has sealed body lowered on armored cable equipped with slowly burning charge of thermal gas-generating substance with ignition assembly, and fire-resistant perforated body connected to lower portion of sealed body. Lower portion of sealed body is provided with membrane, destroyed by given pressure, enough for hydraulic tearing of rocks. Also present is fire-resistant perforated body. It is charged with chemically active fluid placed in easily destructible shell. Charge ignition assembly is placed in upper portion of device. Charge of thermal gas-generating substance has opportunity of movement under effect from weight and reactive traction, during burning of charge, into perforated fire-resistant body. ^ EFFECT: higher oil yield of bed due to forming of additional micro-cracks in face-adjacent area as well as chemical and thermal treatment of productive interval of well. ^ 1 dwg
