The utility model relates to an integrated squeezing and sealing tubular column, which mainly comprises an upper joint, a squeezing and injecting sleeve, a top shoe, a bottom shoe, a slip and a rubber sleeve, is used for sealing a scrapped well and acidizing, plugging and cementing plug operation, and solves the problem that an original construction tool needs to finish the construction operation by two times of tubular columns. According to the integrated squeezing and sealing tubular column, setting, squeezing and sealing and cement injection operation are achieved, and the construction operation and well cementation cost is saved; the alloy slips made of special materials are used, so that the anchoring force of the integrated squeezing and sealing tubular column to the sealing insertion tube is improved; a bidirectional alloy slip structure is adopted, so that the pressing resistance of the integrated squeezing and sealing tubular column is greatly improved, and the tool is ensured to bear high pressure u
