API Oilfield Liner Hanger Deep Wells Liner Top Packer 245×178

Size245×178 Packer Pressure T 30 Sealing Ability 25 MPa Max Od Of Body214Mm Oilfield Liner Hanger

API Oilfield H2s Resistant Liner Hanger for Cementing
Mchanical Liner Hanger,with double cones,double-row slips and double cylinders,is set hydraulically by applying pressure through the run-in string.A setting ball is circulated or dropped to the ball seat built into the landing collar.Applied pressure pushes slips up the cone to the set position.
Features:
1,Theis set hydraulically,applicable to different wells,especially to deep wells.
2,With two different setting mechanisms,the can set easily.
3,Working with SQ setting-ball carrier,the is suitable for applications in horizontal or highly-deviated wells.
4,The piston sealing element is made of nitrile/fluorine rubber for higher pressure and temperature ratings.
5,Main parts are fabricated with high-strength alloy steel providing high burst/collapse resistance.
Property Parameters

Advantages and Features: 

1- For liner cementing of oil and gas water channeling problem provide back-up packer device 

2- Use HNBR rubber packer rubber tube 

3- 50 MPA or voltage, 204 degree heat resistance. 

The liner hanger  with a packer can effectively seal the overlapping annular space and prevent the migration of fluid/gas between the casing and the formation from causing gas channeling.

After cementing, set the packer. Lift the drill string up to create a bell mouth and circulate excess cement slurry without affecting the lower formation.

Principle : 

After the tail pipe is lowered to the designed position, follow the normal procedure of setting, reversing, cementing, and bumping, lift the drill string up to extend the sealing block on the tool, and seat it on the upper end face of the return tube. Lower the drill string, cut the pins, and the rubber tube expands under external force, forming an effective seal between the upper casing and the return tube.
