The invention provides a gas well auxiliary liquid carrying system comprising a gas well and a gas-liquid separating device. A Christmas tree is plugged at a well mouth of the gas well, and the gas-liquid separating device comprises an input end, a first output end and a second output end. One end of an oil pipe penetrates through the Christmas tree and stretches into the gas well, and the other end of the oil pipe is connected with the input end. One end of a return pipe penetrates through the Christmas tree and stretches into an oil gas reservoir in the gas well, and the other end of the return pipe communicates with the first output end through a blower pump. A one-way valve which only allows a gas flow to flow to the gas well from the blower pump is arranged on the return pipe and located between the blower pump and the Christmas tree, the second output end is connected with a remote gas storing end through a gas delivery pipe so as to deliver gas to the gas storing end, and a liquid discharging pipe is arranged at the lower end of the gas-liquid separating device and downwards connected to a stop valve. The gas well auxiliary liquid carrying system has the beneficial effects that the cost is low, the applicability is wide, gas production can be circularly and continuously conducted, and meanwhile gas-liquid sufficient separating can be achieved.
