Device and method for measuring hole erosion non-uniformity

The invention discloses an eyelet erosion non-uniformity measuring device and method. The device comprises a sand mixing tank, an injection pump, an experimental pipeline and a liquid recoverer, the sand mixing tank, the injection pump, the experimental pipeline and the liquid recoverer are sequentially connected through pipelines; an outlet of the liquid recoverer is connected with a liquid return port of the sand mixing tank to form a liquid circulation loop; an outlet of the injection pump is connected with a head pipeline of the experimental pipeline, and the tail of the experimental pipeline is closed; at least two groups of hole mounting ports are distributed on the pipe wall of the experimental pipeline; the at least two groups of hole mounting ports are spirally and uniformly arranged on the experimental pipeline; the hole mounting opening is suitable for detachably mounting a hole sample; the sand mixing tank is suitable for mixing a fracturing fluid and a propping agent to obtain a sand-carrying flu
