摘要： A bridge plug includes a mandrel, a setting cone disposed at least partially about the mandrel, a slip ring and a sealing element disposed at least partially about the setting cone, and a guide shoe operatively coupled to a downhole end of the mandrel. The bridge plug is actuatable from a run-in state to a deployed state, wherein, when the bridge plug is in the deployed state, the mandrel is axially movable relative to the setting cone to seal or open a flow path through the bridge plug.
