Patent

CA 2309513

An improved liner hanger setting mechanism is provided. The setting mechanism of the present invention is basically comprised of a tubular pump down plug receptacle having a plug seat defined therein. A cylindrical pump down setting plug having a central flow passage and a rupturable member disposed therein to prevent flow, therethrough is dropped into a work string and the tubular plug receptacle. The pump down setting plug will engage the plug seat and pressure can be increased to the setting pressure required to set a hydraulically actuated liner hanger. The pressure can then be further increased to the rupture pressure of the rupturable member to provide for full bore flow through the pump down setting plug.
