Beschreibung
Zusammenfassung:	FIELD: oil and gas production, particularly perforators and permeators. ^ SUBSTANCE: device comprises body with drilling unit for drilling device rotation and advancing, fixing mechanisms for body connection to well bore wall and body suspension device made as logging cable. Drilling means of device is made as bar provided with sprocket connected to one bar end attached to slide. Sprocket is kinematically connected with drilling unit. Slide is connected to drilling unit and is supported by guiding means secured to body in longitudinal direction. Flexible working tool is arranged around the bar. Longitudinal guiding slot is made in the bar. The guiding slot receives carriage mounted on axis secured to body. ^ EFFECT: provision of continuous drilling, possibility to remove drilling means from well, prevention of device wedging, decreased cutting area and reduced working tool rotation force. ^ 2 cl, 4 dwg
