Small-displacement continuous acidification plug removal equipment system for water injection well of oil field

The invention relates to the technical field of acidification unblocking equipment systems, in particular to an oilfield water injection well small-displacement continuous acidification unblocking equipment system which comprises an acid liquid tank, a first opening is formed in the top of the acid liquid tank, and a tank cover corresponding to the first opening in position is mounted at the top of the acid liquid tank through a lock catch; an acid-resistant pump is arranged on one side of the acid liquor tank, the acid-resistant pump and the acid liquor tank are connected through an acid-resistant pipeline, and a flow adjusting mechanism is arranged on one side of the acid-resistant pump. The flow adjusting mechanism is arranged and used for controlling acid liquor to flow into the flow collecting cover from the opening distance between the flow baffle and the flow collecting cover, the speed of the acid liquor flowing into the flow collecting cover can be adjusted along with adjustment of the opening distan
