The invention discloses a liquid-unloading gas recovery pipe string. The liquid-unloading gas recovery pipe string is composed of a pipe body with a liquid-controlled pipeline, and the pipe body is sequentially provided with a subsurface safety valve, a sliding sleeve, a positioning seal and a first packer; a second packer, a hanger, a speed pipe string and a blanking plug are arranged between thesubsurface safety valve and the sliding sleeve; an upper body of the hanger is connected into the pipe body sequentially through the second packer and the safety valve, and a lower body of the hangeris connected with the blanking plug through the speed pipe string; and an eddy current tool is movably connected to the interior of the hanger. According to the liquid-unloading gas recovery pipe string, the flow velocity of fluid in a wellbore of a gas well is increased, so that the liquid carrying ability of the gas well is improved, and requirements of liquid-unloading gas recovery in an offshore oilfield gas well are met.
