Liner hanger packer-set 

LINER HANGER, PACKER-SET , OILFIELD TOOLS, WELL CONSTRUCTION, CEMENTING TOOLS, HYDRAULIC SETTINGS

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.
