Coiled tubing hydraulic jet bottom seal dragging fracturing tubular column

The invention discloses a coiled tubing hydraulic jet bottom seal dragging fracturing tubular column which comprises a hydraulic spray gun (2) which is a spray gun single body or a spray gun module formed by connecting the spray gun single bodies in series. The hole distribution modes and the hole distribution numbers of all the spray gun single bodies in the spray gun module are the same or different, and the distances between the spray holes (2-5) of the adjacent spray gun single bodies are the same or different; the problem that a conventional bottom seal dragging fracturing pipe column cannot meet the construction requirement under the condition that shale oil returns after high pressure due to the fact that the perforation number of spray guns in the pipe column and the hole distribution mode cannot meet the design requirement when an existing fracturing pipe column is used for a large-thickness reservoir and the drilling rate of the reservoir is high is solved. 本申请公开了一种连续油管水力喷射底封拖动压裂管柱，包括水力喷枪（2），所述水力喷枪（
