Liner Hangers

Noncemented liner hanger PHN1

The PHN1 liner hanger is used to RIH and hang non-cemented liners. It is manufactured in
2 modifications, differed by the type of internal space shut-off:

  • by throttling valve, which gets closed by increased circulation rate;
  • by pumping of cementing plug or activation ball, that land into a landing seat located at
    the bottom of hanger mandrel.
  • PHN1 is equipped with UIF (unit of isolation of filters), allowing to circulate through the
    liner shoe.

PHN1 hanger consists of 4 functionally independent parts:

  • anchor to hang the liner assembly in the casing string;
  • hydro-mechanical packer to isolate annular space;
  • hydraulic release mechanism that allows to RIH liner assembly, circulate, activate
    anchor/packer by hydraulic pressure and, then, disconnect the drill string from PHN1
    by applying hydraulic pressure.
  • mechanical release to back up a hydraulic disconnection mechanism.

Design of PHN1 is practically identical to that of PHCZ1, except that at the end of tool
mandrel, there installed a landing seat or a throttling shut-off valve, instead of hollow
cement plug, and mandrel has circulation ports.
