Plug-in coiled tubing induced-spraying device

The utility model discloses a plug-in coiled tubing induced-spraying device. The plug-in coiled tubing induced-spraying device comprises an outer tubular column, a coiled tubing and a coiled tubing injector, wherein the coiled tubing is fed inside the outer tubular column through the coiled tubing injector; a positioning seal working barrel is arranged in the outer tubular column; the periphery of the positioning seal working barrel is in sealing fit with the inner circumference of the outer tubular column; an inserted sealing rod is arranged at the lower end of the coiled tubing; the inserted sealing rod is provided with a through hole communicated with the coiled tubing along the axial direction; and when the coiled tubing injector feeds the coiled tubing downwards to a preset position in the outer tubular column, the inserted sealing rod is inserted into the seal work barrel, and the periphery of the inserted sealing rod is in sealing fit with the inner circumference of the positioning seal working barrel. According to the device, the problems that water seepage at the stratum and the liquid carrying effect of a large-diameter tubular column is not ideal in a gas well test can be solved, and conventional gas lift induced spraying, production seeking and testing can also be carried out, so that the multifunctional aim of the tubular column is fulfilled.
