A kind of polymer flooding water flooding dual function transfer plug. The utility model mainly solves the problem that the edge measuring and adjusting device of a polymer injection well is not provided with an adjustable plugging device; when the water injection is used, the existing stopper has a small automatic adjusting range, and the blocking device is easy to move up and down, and the plunger is easy to rotate. It is characterized in that the pressure cap (4) with a convex edge of axial plunger (16); (7) the lower part of the conical head, cone arc transition, the plunger (7) outside the main cylinder (2) with lower limit sleeve centralizer (6), and the anti rotation pin (13) fixed. Anti rotation pin (13) in the Yu Zhusai (7) axial keyway (14); cam (8) extension card (15) and the cam angle (8) axial vertical distance from the L center is 3 mm. The polymer flooding water flooding dual function transfer plug in injection and injection when the automatic adjustment range, plug a good overall stability, long service life, suitable for injection or injection.
