Coiled tubing device has been pressed out in area

The utility model relates to a coiled tubing device has been pressed out in area belongs to gas -field exploitation technical field. Utilize injection head -clamp on the coiled tubing workover rig to hold the connector of the instrument of sending into and intraductal blanking plug, squeeze into coiled tubing with intraductal blanking plug inside, pouring into the overhead instrument of sending into of carrying into, making intraductal blanking plug sit and seal, the injection head increasing power of lifting makes intraductal blanking plug and sends into the instrument and breaks away from, and intraductal blanking plug is stayed inside the coiled tubing to sealed coiled tubing, penetrate the plug in the coiled tubing end to draw the ware with the wild card and install at continuous pipe end head, hang the wild card vara with the crane and pull out the ware and lift coiled tubing, make the slips unfreezing of hanging coiled tubing, the coiled tubing that will rise out is the anti - operation window of wearing, preventer, the first -class equipment of injection in proper order, then change to instead and pour into the head into and continue to lift coiled tubing, and the pipe that will constantly rise out simultaneously twines the cylinder on the coiled tubing workover rig.
