Slip packer for gas well fracture

The utility model relates to the field of oil production engineering, and belongs to a slip packer for gas well fracture. The slip packer solves the problems that a past gas well fracture packer fails in sealing due to repeated sealing and unsealing during fracture, and a next packer can be unsealed as soon as one layer is pressed. A sand blasting body 3, a protecting ring 10, a side rubber cylinder 11, a middle rubber cylinder 12, a spacer ring 13, a sealing piston 14, a clamping piston 15, an upper cone 19, a slip 21, a slip hanger 23 and a lower cone 25 are sequentially sleeved outside a central tube 2 of the slip packer, the upper cone 19 is connected with the clamping piston 15 in a threaded manner, and the slip hanger 23 is fixed to the upper cone 19 by the aid of an upper clamping pin 20. The slip packer is mainly applied to a gas well fracture process, and has the advantages of good temperature and pressure resistance, safe and reliable process and the like.
