Abstract:
The present disclosure provides a fracturing bridge plug, and belongs to the technical field of downhole plugging devices of oil and gas fields, which solves technical problems that the existing packer rubber is axially compressed, a bridge plug is relatively long, and a dissolving or drilling effect is not ideal. The fracturing bridge plug comprises a cone, an upper cone, a seal assembly, a lower cone, a slip, a locking ring and a guide shoe, a matching surface of the upper cone and the seal assembly is a first ramp, one end, far away from the lower cone, of the first ramp is a large end while one end, close to the lower cone, thereof is a small end, and the diameter of the first ramp from the large end to the small end is gradually reduced.
