| description | The invention belongs to the technical field of petroleum downhole operation equipment, aims to solve the problems that an existing sleeve wall scraping tool is complex in structure and large in operation risk, and provides a hydraulic excitation type sleeve wall scraping device which comprises an upper connector, a body, a piston rod, an upper pressing plate assembly, a scraper, a lower pressing plate assembly, a guide body and a lower connector. A through hole is formed in the body and comprises a first cavity section, a first hole section, a second cavity section and a second hole section. A side groove for accommodating the scraper is formed outside the body; a groove is formed in the side part of the piston rod; a bulge is arranged on the inner wall of the scraper; when the actual displacement is larger than the set displacement, the piston rod moves away from the upper connector under the action of external pressure, the elastic piece is in a compressed state, the groove is separated from the protrusion |
