| description | The utility model provides a horizontal well repeated fracturing tool which comprises a pipe body, an annular space is formed between the pipe body and a shaft, and an inlet allowing fracturing fluidto flow in and an outlet allowing fracturing fluid to flow out are formed in the side face of the pipe body. A top packer; a middle packer; the slip packer, the top packer, the middle packer and the slip packer are sequentially arranged on the outer side of the pipe body in a sleeving mode at intervals in the direction, away from a well mouth, of the pipe body, the top packer is located between the well mouth and a perforation closest to the well mouth, and a fracturing area used for containing the perforation to be modified is formed between the middle packer and the slip packer. An inlet islocated between the top packer and the wellhead, and an outlet is located in the fracturing area. The problem that in the prior art, a mechanical packing mode cannot meet the requirement for repeatedfracturing is solved.
