The invention discloses a method for producing gas by using a production pipe column of a parallel double-pipe gas well. The method is characterized by comprising the following steps that: a large oil pipe and a small oil pipe are hung in a sleeve through a double-pipe oil pipe; the sleeve is packed bya double-pipe packer; in the early stage of putting a gas well into production, when the yield is high, a first underground safety valve arranged on the large oil pipe and a second underground safety valve arranged on the small oil pipe are opened, so that the large oil pipe and the small oil pipe simultaneously perform gas production work; in the middle stage of the gas production operation of the gas well, the yield is gradually reduced, so that the large oil pipe continuously performs gas production work, and the small oil pipe stops the gas production; in the late stage of the gas production operation of the gas well, when liquid is accumulated in the gas well, the large oil pipe stops the gas production, and the small oil pipe starts to perform the gas production work; when the accumulated liquid in the gas well is much, and the liquid-carrying production cannot be carried out, the sleeve is subjected to annular gas injection, and a gas lifting mode is used for performing water discharge gas production through the small oil pipe. The gas production method has the characteristics that the gas production speed is high; the operation cost is low; the environment pollution is little; and the well workover is not needed in the late stage.
