  • Patent number: 12326067
    Abstract: Disclosed is an infinite-stage fracturing sliding sleeve. The infinite-stage fracturing sliding sleeve includes an outer cylinder, an inner cylinder, a sliding cylinder, an elastic element and a counting mechanism, wherein the inner cylinder closes a fracturing hole on the outer cylinder, and a lower end of the sliding cylinder is provided with an elastic claw. When the number of fracturing balls is less than a preset value, the elastic claw of the sliding cylinder moves in a reduced diameter section and an expanded diameter section in the outer cylinder. After the fracturing sliding sleeve is adopted, the fracturing sliding sleeves of all stages may be driven to open by fracturing balls of the same size, and there is no size difference between the fracturing sliding sleeves of all stages, so that the number of fracturing stages is not limited.
