The utility model discloses a continuous auxiliary gas lift drainage gas recovery compressor, which belongs to the field of gas lift drainage gas recovery of an oil and gas field. The device is connected with an output pipeline at the mouth of a well, takes natural gas inside the well or a pipeline as engine power, and drives a gas compressor to inject the natural gas into a gas well oil jacket annular space. The device at least comprises a power unit, a first buffer tank, a second buffer tank, a flowmeter, a primary separator, a secondary separator, a tee joint, a related pipeline, a related connection hose and a related valve. During a gas injection process, liquid carrying capacity can be provided or increased, redundant gas cannot enter into a stratum, accumulated liquid in a shaft and an area close to the well can be gradually drained, and in addition, the accumulated liquid cannot be formed again. The power unit uses less gas, so that the production and operation cost can be effectively reduced; and a s
