The invention belongs to the technical field of downhole throttling processes, and particularly relates to a coiled tubing throttling device removing and drainage gas production integrated pipe columnand a using method thereof. According to the coiled tubing throttling device removing and drainage gas production integrated pipe column and the using method thereof, through the technical scheme that a coiled tubing, a connector, a hydraulic safety joint, a back pressure valve, a bumper jar, a screw motor and a grinding shoe are sequentially connected to the coiled tubing from top to bottom, downhole throttling device removing is not influenced by the situations such as downhole fluid loading, and the coiled tubing throttling device removing and drainage gas production integrated pipe columnand the using method thereof are suitable for removing a downhole throttling device any well condition; after the downhole throttling device is removed, the pipe column is used as a production pipe column, and the operation cycle is shortened; and the characteristic that the diameter of the coiled tubing is smaller than the diameter of conventional production tubing is utilized, so that the coiled tubing drainage gas production technology is realized, the liquid carrying capacity of a gas well is remarkably improved, formation water is drained from a wellbore in time, and the production cycleof the gas well is prolonged.
