Gas lift plunger assembly arrangement
A elongated plunger assembly for pressurized, conduit-enclosed travel utilized in recovery of hydrocarbon deposits in a ground penetrating oil or gas well. The plunger comprises an elongated mandrel, a plurality of radially movable curvilinear wear pads circumferentially disposed adjacent each end of the elongated mandrel, a pad-edge retaining housing extending on at least one end of the elongated mandrel to enclosably retain the longitudinally distal end of a circumferential array of wear pads onto the mandrel, and a centrally disposed wear pad securement ring arrangement to permit release of a worn wear pad, replacement of the worn wear pad at an inner longitudinal edge thereof, thus to permit simple field-accessable removal and replacement of any particular “conduit-worn” “wear” pad from the mandrel of the plunger.
