High-pressure rotational flow near-well blockage removing device

The utility model discloses a high-pressure rotational flow near-well unblocking device, and relates to the technical field of underground unblocking devices. The device comprises a high-pressure rotational flow generator, a connecting piece and a one-way liquid inlet valve, the high-pressure rotational flow generator is provided with a fixed end and a movable end capable of rotating relative to the fixed end, the fixed end of the high-pressure rotational flow generator is communicated with the connecting piece through a first packer, and the movable end of the high-pressure rotational flow generator is communicated with the one-way liquid inlet valve through a second packer; and packers arranged at the two ends of the high-pressure rotational flow generator block the blocked well sectionand the non-blocked well section. According to the utility model, the packers for blocking the high-seepage well section and the low-seepage well section are arranged at the two ends of the high-pressure cyclone generator, so
