The present invention provides a moving plunger for gas well production with water withdrawal which is simple in structure and good in accumulated fluid withdrawal effect. The moving plunger comprises a fish head, a sealing rod in the fish head, a retaining sleeve which is arranged between the fish head and the sealing rod and used for limiting the movement range of the sealing rod, wherein the lower part of the fish head is screwedly connected with an outer sleeve, a drop bar is movably arranged in the outer sleeve; and the outer part of the outer sleeve is sleeved with an elastic sealing claw. The tool vertically floats due to the pressure in well, so that the shaft accumulated fluid is lifted and discharged through a well opening, and finally natural gas is developed or water flooding of other gas wells in the same air reservoir is delayed and avoided, so as to improve the production state of the whole air reservoir and increase the final production rate of the air reservoir. The moving ...
