The reservoir transformation filtering device comprises a long cylinder, a groove is formed in the inner wall of the long cylinder, a first filter screen is arranged in the groove, the first filter screen is connected with the groove through a spring, and the first filter screen is made of an elastic material; a sleeve is arranged in the long cylinder, the side wall of the sleeve is connected with the inner wall of the long cylinder through a transverse shaft, a rotating shaft is rotationally connected in the sleeve, one end of the rotating shaft penetrates through the sleeve and is fixedly connected with fan blades, and the other end of the rotating shaft is fixedly connected with a rotating rod; the first filter screen is fixedly connected with an auxiliary magnetic block, the surface of the rotating rod is fixedly connected with a main magnetic block, and the sides, adjacent to the main magnetic block, of the auxiliary magnetic block are homopolar, so that the technical problem that in the fracturing transformation process, impurities exist when liquid is injected and passes through the long cylinder, so that the pump injection liquid supply efficiency becomes low, and the reservoir fracturing transformation effect is affected is solved. According to the reservoir transformation filtering method disclosed by the invention, under the pressure of water flow, the first filter screen, the main shaft and the auxiliary shaft are driven to move, limiting on the rotating shaft is relieved, and the fan blades are driven to rotate, so that the fan blades drive the shifting rod to scrape sand and stone particles on the surface of the first filter screen.
