Abstract
An all-metal bridge plug with a self-contained ball adapted to casings with various specifications, including a locking cap, an upper cone, a sealing ball, a metal sealing ring, a locking joint, a lower cone, a slip spider, a base, and a pull rod. One end of the pull rod may be connected with a seating tool, and the other end of the pull rod may be connected with the base through a first outer thread. The locking cap, the upper cone, the locking joint, the lower cone, and the slip spider may be sleeved on the pull rod sequentially from left to right along an axial direction of the pull rod. The upper cone, the sealing ball, the metal sealing ring, the locking joint, the lower cone, the slip spider, and the base may be manufactured from magnesium-based and aluminum-based dissolvable metal materials that dissolve automatically after fracture is completed.
