Bridge plug

The invention provides a bridge plug. The bridge plug comprises a central pipe made of light alloy. A tool connector is arranged at the upper end of the central pipe and arranged on the outer side of the central pipe in a sleeving mode. The bridge plug further comprises a first slip assembly and a second slip assembly which extend in the axial direction of the bridge plug. The first slip assembly and the second slip assembly are both arranged on the outer side of the central pipe in a sleeving mode, and the first slip assembly is connected with the tool connector. The central pipe of the bridge plug is made of the light alloy, thereby being capable of being drilled easily; the drilling time of the bridge plug is shortened, and metal chips generated during grinding and milling can be conveniently discharged to the ground. The bridge plug has the characteristic of being rapidly drilled, so that the production time is effectively shortened, and the economic benefits are increased. 本发明提供了一种桥塞，包括中心管，中心管由轻质合金制成；其中，
