Abstract
The invention relates to oil and gas industry, to devices for well workover, in particular to devices for cleaning walls of a production casing from asphalt-resin-paraffin deposits (ARPD), filtering a well fluid from floating deposits and foreign matter, cleaning a well bottom from dense bridging, cleaning filtration channels of a bottom zone of a productive formation from colmatage deposits and mechanical impurities in one trip when performing regular well repairs and well workovers. A complex of multifunctional well clean-up is described, which includes a collar packer with a through channel between an upper outlet perforated nipple and a lower slotted filter, an internal connecting pipe that keeps tightness of the entire assembly having a throttle and a knock-out valve installed on its upper end, and a device for dense bridging removal installed on its lower end via an adjustable hydraulic bailer and a valve system. The technical result: obtained is a multifunctional, simple in design device to clean-up a well and a bottom zone of productive formation within one trip.
