INTEGRATED DEVICE FOR PROCESSING productive strata

摘要

The invention relates to a jet devices used in the oil industry. Well jet device comprises a column of tubing and mounted thereon sequentially from top to bottom: jet apparatus with an active nozzle and a mixing chamber with a diffuser, a packer, the ink jet unit is made without communication with the blew, the active nozzle and a mixing chamber with a diffuser jet apparatus fitted in the functional insert, in addition to the column of tubing production string installed portion purification device for planting packer. EFFECT: increased productivity and reduced time to carry out works in the borehole by expanding the functional capabilities of a well jet unit. Expansion capability downhole jet unit is due to the fact that the active nozzle and a mixing chamber with a diffuser installed in the functional insert, sealing the tubing is not disturbed. This allows to use the device for cleaning the packer landing site (mechanical scraper hydromechanical scraper, the scraper type crown) in an installation, and to prepare (purify) the inner surface of the production tubing for landing of the packer. 1 bp, 2 fig.
