The invention belongs to the technical field of acidification unblocking liquid adding, and discloses an oilfield acidification unblocking liquid matched adding device and a using method thereof.The oilfield acidification unblocking liquid matched adding device comprises a liquid storage tank for storing acidification unblocking liquid, a liquid outlet of the liquid storage tank is connected with a liquid pump, the output end of the liquid pump is connected with a liquid drainage pipeline, and the acidification unblocking liquid flowing out of the liquid drainage pipeline enters an oil well; the liquid discharge pipeline is connected with a pressure gas pipeline in a bypass mode, and pressure gas entering the liquid discharge pipeline from the pressure gas pipeline pushes the residual acidification unblocking liquid in the liquid discharge pipeline to be completely discharged. According to the device, the acidification unblocking liquid is stored in the liquid storage tank, when the acidification unblocking l
