| description | An upper connector, an upper pull rod, a releasing pull ring, a lower pull rod and a lower cone of the drillable bridge plug are sequentially connected through screw threads, a clamping spring seat ofthe drillable bridge plug is axially fixed to the upper portion of the lower pull rod through a fishing head, a second shear pin and a locking block, and the clamping spring seat is sleeved with a clamping sleeve. An upper rubber cylinder seat, a rubber cylinder, a liner tube, a lower rubber cylinder seat, an upper cone, a slip sleeve, a slip and a baffle ring are sequentially connected outside the lower pull rod of the ferrule, the upper portion of the ferrule is fixed to the lower portion of the upper connector through a first shear pin, and a sealing piston is arranged between the upper connector and the upper pull rod. The drillable and removable bridge plug is simple in structure, high in pressure bearing capacity of the rubber cylinder and not prone to shoulder protrusion; the fishing operation can be reali |
