description The invention discloses a horizontal well strong magnetic die, which comprises an upper connector, a core shaft and a lower connector connected sequentially, wherein an outer cylinder is sleeved outside the core shaft; a plurality of spiral grooves are arranged on the peripheral face of the outer cylinder at intervals; a plurality of counter bores are arranged in each spiral groove at intervals; a magnet is arranged in each counter bore. The magnets of the horizontal well strong magnetic die adopt a spiral line distribution mode, so that mutual interference between the magnets is avoided, and an adsorption plane is a magnetic end face; a special-shaped spiral winding raised rib structure on the surface of the outer cylinder enables a tool to have a centralizing function and to be automatically rotated in a well entering process; compared with similar products, the tool has large adsorption capacity, relatively thorough adsorption cleaning, and is suitable for fishing metal chippings in a vertical shaft, a hor
