Combination Pump Down Plug


The Combination Pump-Down Plug is designed to wipe combined drill pipes during liner hanger cementation. The two-stage design plug combines different sized rubber fins together. When the plug lands on the X-Sub, the lower section is sheared off form the upper section. The lower section wipes the small drill pipe,lands and locks in the liner wiper plug. The combined plugs wipe the liner and land in the landing collar to complete cement displacement. The combination pump-down plug has reliable isolation and displacement performance.
