description FIELD: oil and gas production, mining industry. SUBSTANCE: in process of well cleanup clogging is ripped by rotation of pipes with fluke and ripper without opening of fluke. Clogging is sucked right after ripping through ripper and holes located at level of perforation holes in well casing. Fluke is removed from well. It is possible to fill up part of fluke and pipes above it with well fluid before start of ripping by short-time resting of ripper in clogs of sump and opening of fluke. Step-by-step well cleanup is also possible by ripping and suction of portion of clogging with repetition of cycles of ripping and suction till well is cleaned or fluke is filled. EFFECT: enhanced efficiency of well cleanup. 2 cl, 1 dwg
