Large drift diameter rapid drilling bridge plug for fracturing

The invention relates to the technical field of oil production engineering of oil fields, in particular to a large drift diameter rapid drilling bridge plug for fracturing of a casing pipe horizontal well. The invention aims at solving the problems that at present, a large drift diameter rapid drilling bridge plug applied to multi-segment large-scale fracturing modification of a horizontal well does not exist. The large drift diameter rapid drilling bridge plug is composed of a soluble ball 1, a central tube 2, a pushing ring 3, split-type slips 4, hoop rings 5, cone bodies 6, protecting copper rings 7, rubber sleeves 8 and a guide connector 9, wherein the central tube 2 is sequentially connected with one pushing ring 3, one split-type slip 4, one cone body 6, one protecting copper ring 7, one rubber sleeve 8, the other rubber sleeve 8, the other protecting copper ring 7, the other cone body 6, the other split-type slip 4 and the guide connector 9 from top to bottom. The large drift diameter rapid drilling bridge plug for fracturing has the advantages of being simple in structure, high in bearing capacity, strong in adaptability, rapid in drilling and milling, large in drift diameter, light in mass and the like.
