| description | The utility model relates to a coiled tubing bottom seal dragging fracturing tool, which comprises a drifting and pipe scraping tool string and a fracturing tool string, and is characterized in that the drifting and pipe scraping tool string comprises an outer slip joint, a mechanical hydraulic double-acting release, a centralizer, a drift diameter gauge, a pipe scraper and a guide shoe which are connected in sequence; the fracturing tool string comprises an outer slip connector, a mechanical hydraulic double-acting release, a centralizer, an anti-splash spray gun, a balance valve, a bottom packer, a coupling positioner and a guide shoe which are connected in sequence. Sand-carrying fluid is added into the continuous oil pipe, perforation is conducted through the anti-splash spray gun, fracturing is conducted through annulus large-displacement sand adding, setting of the bottom packer is stable and reliable, deblocking and layer transferring are rapid, rapid flowback is achieved after fracturing, and pollutio |
