The invention discloses an upstream injection sucker-rod pump same well mining and injecting device. The upstream injection sucker-rod pump same well mining and injecting device comprises two following components including a separation component and a swabbing component, wherein by means of the separation component, a stock solution generated in a working well can be separated into different separation products with main components being different in performance underground; and by means of the swabbing component, two functions can be achieved in the upstream process of a movement assembly contained in the swabbing component, one function is that power needed by stock solution separation and a temporary storage space for the separation products are provided for the separation component, and the other function is that the different separation products generated in the previous working circulation are pressurized at the same time. The upstream injection sucker-rod pump same well mining and injecting device is used for a sucker-rod pump mining well, the components of the products in the well are separated underground, when a working bolt support moves upwards, the separation product with relatively large expected component content is mined, the separation product with relatively large unexpected component content is synchronously reinjected, the mining and injection actions can acquire sufficient power through ground hoisting equipment, and the mining and injecting flow ratio can be directly and effectively controlled through a working cavity volume ratio inside the device.
