The utility model relates to an underground plugging tool for an oil well, in particular to an integrated dust squeezing bridge plug capable of being taken out. The dust squeezing bridge plug comprises an upper connector, a liquid cylinder, a piston mandrel, a pushing cylinder, an inserting pipe, a setting connector, a setting shear pin, a deblocking head, a lock ring, a deblocking shear pin, a lock block, a sand-prevention rubber sheet, a lock sleeve, a limiting ring, a cone body, a slip, a mandrel, a slip barrel, a sealing sleeve, a sliding sleeve mandrel, rubber barrels, a partitioning ring and an end cap. The upper end of the inserting pipe is in threaded connection with the lower end of the piston mandrel. The lower end of the inserting pipe is in threaded connection with the upper end of the sliding sleeve mandrel. The lower end of the sliding sleeve mandrel is in threaded connection with a backstop lock ring. A control sliding sleeve is connected in the sliding sleeve mandrel through a pin. A switch sliding sleeve is arranged between the sealing sleeve and the sliding sleeve mandrel. The switch sliding sleeve and the backstop lock ring are arranged in the end cap respectively. The mandrel is arranged on the outer side of the inserting pipe. The upper end of the mandrel is in threaded connection with the inserting pipe. The integrated dust squeezing bridge plug is stable in performance, bridge plug setting and dust squeezing working can be completed through one pipe column, and the bridge plug can be taken out for recycling after dust squeezing plugging working.
