Liner Hangers

Hydro-mechanical cemented liner hanger PHGMC

Hydro-Mechanical Cemented Liner Hanger PHGMC is designed for RIH, hanging and sealing in of cementing liner, performing of technological operations connected with cementing and sequential actuation of an anchor unit and a packer unit and further automatic disconnection of transport string from the liner and transport string pulling out.

PHGMC hanger is a complex of four stand-alone and independent units:

• hydraulic anchor;
• hydraulic disconnection device;
• mechanical packer;
• mechanical release unit doubling the hydraulic one.

The hanger is provided with a number of interlocks: hydraulic breaking is protected against early actuation before the hollow suspended plug is cut, the packer may be actuated only after disconnection.

The hanger consists of two parts: adjustment tool and the hanger itself, the latter includes packer unit, anchor unit and lead-in funnel. When using hangers like PHGMC the following technological operations are performed:

• RIH of the device as a part of a transport string liner;
• performing of washovers with limited pressure (no more than 75% of anchoring pressure);
• washover at the bottomhole without pressure limits (anchor actuation changes annular space insignificantly);
• performing of liner cementing with running of the cementing plug after the injection of the cement slurry for its separation from the displacement fluid;
• displacing the cement slurry to the outer annular space of the liner with limited displacement pressure after the suspended plug is cut off (no more than 75% of disconnection pressure) and receiving of “ bump” signal;
• anchor unit actuation with internal overpressure build-up to 14 MPa;
• hydraulic breaking unit actuation with pressure build-up to 20 MPa;
• mechanical breaking unit actuation with transport string rotation to the right;
• packer unit actuation by partial uploading of the transport string weight onto the “head” part of the liner;
• washover and pulling out of the transport string.
