The invention belongs to the technical field of oilfield water injection, and particularly relates to a small-scale clear water injection station. The small-scale clear water injection station comprises a water storage unit, a water treatment unit, a water injection unit and a house. The house at least comprises an upper layer and a lower layer. The water storage unit is installed in the upper layer of the house. The water treatment unit and the water injection unit are installed in the lower layer of the house. The water storage unit is sequentially connected with the water treatment unit andthe water injection unit. The problems that by adopting temporary water injection prying, adaptability is poor, the occupied area is large, the construction period is long, fast production cannot beachieved, reusing is not achieved after relocation, and the project investment is increased are solved; and according to the small-scale clear water injection station, the occupied area is small, theconstruction period is short, fast production can be achieved, reusing is achieved after relocation, and the project investment is decreased.
