The invention discloses a short-time throttling tubular column and method. The short-time throttling tubular column comprises a tubular column body; a ball seat is connected in the tubular column body; a sand-blasting device is connected onto the tubular column body below the ball seat; an upper packer is connected outside the tubular column body above the ball seat; a lower packer is connected outside the tubular column body below the sand-blasting device; a soluble ball is placed in the ball seat; a plurality of through holes are formed in the soluble ball; and the central lines of the plurality of through holes intersect at the center of the soluble ball. By the aid of the through holes of the soluble ball, when metal sealing is realized between the soluble ball and the ball seat, certain liquid passing passages are still reserved, so that the sufficient throttling differential pressure can be formed at the small displacement, the upper packer can be used for realizing setting, after the displacement is increased, the soluble ball is dissolved, the sufficient throttling differential pressure can be provided by the shrinkage diameter of the ball seat for setting of the upper packer, and thus small-displacement setting of the upper packer and large-displacement pumping fracturing are realized.
