DAMPENER LUBRICATOR FOR PLUNGER LIFT SYSTEM

摘要

A lubricator for use in a plunger lift system includes a tubular body having an outlet formed through a wall thereof and a bore therethrough. The bore is closed at an end thereof. The lubricator further includes a striker assembly disposed within the bore. The striker assembly includes a dampener housing longitudinally movable relative to the tubular body between a ready position and a stroked position and a choke plate. The choke plate: is disposed in the dampener housing, separates a bore of the housing into an upper hydraulic chamber and a lower hydraulic chamber, and has one or more orifices formed therethrough. The striker assembly further includes a dampener support rod connecting the choke plate to the tubular body. The orifices are sized to dissipate kinetic energy of a plunger striking a lower end of the dampener housing.

1. A lubricator for use in a plunger lift system, comprising:
a tubular body having an outlet formed through a wall thereof and a bore therethrough, the bore closed at an end thereof; and a striker assembly disposed within the bore, the striker assembly comprising:
a dampener housing longitudinally movable relative to the tubular body between a ready position and a stroked position;a choke plate disposed in the dampener housing, separating a bore of the housing into an upper hydraulic chamber and a lower hydraulic chamber, and having one or more orifices formed therethrough; anda dampener support rod connecting the choke plate to the tubular body, wherein the orifices are sized to dissipate kinetic energy of a plunger striking a lower end of the dampener housing and moving the dampener housing from the ready position to the stroked position.
