A portable multipurpose pneumatic pump station device comprises a hydraulic control system and a pneumatic control system. In the hydraulic control system, water is injected into a working portion through a pneumatic control switch handle after passing a liquid inlet, a ball valve, a pneumatic control hydraulic reversing valve, an emulsion automatic proportioning device, a one-way valve and a pressure multiplier; in the pneumatic control system, one branch of compressed air after passing an air inlet enters the pressure multiplier through the pneumatic control hydraulic reversing valve while another branch of the compressed air after passing the pneumatic control switch handle enters the pneumatic control hydraulic reversing valve and a pneumatic control reversing valve. The portable multipurpose pneumatic pump station device is light in weight and convenient to maintain, and workload and construction cost of downhole temporary supporting are reduced effectively; operation is simple, and connection and disconnection of a hydraulic pipeline and an air compression pipeline can be controlled at the same time; needs on downhole safety are met, and stepless speed regulation can be realized; the portable multipurpose pneumatic pump station device is energy saving, environment friendly and low in noise and can work by using a certain amount of compressed air, and emulsion rather than hydraulic oil is used, so that secondary pollution is avoided; the portable multipurpose pneumatic pump station device can be multipurpose by modifying, has wide popularization and application prospect and is fully utilized.
