Expandable Liner Hanger

What Is An Expandable Liner Hanger ?　　

Expandable liner hanger is designed for complex applications. Such as deep water, oil and gas challenging conditions.
　　The expandable liner hanger is an integrated hanger packer system.It is a one-piece structure. So it can effectively improve the whole strength. Also it can solve the annular leaking problem between the previous layer casing and the after layer for side tracking well.
　　Elastoplast elements are bonded on to the hanger body itself. When the liner hanger body is expanded, the Elastoplast elements are compressed in the annular space. It can provide primary annular isolation at liner top.

Specifications

Features

1. It have good sealing hang function; it can completely slove the annular leaking problem between the previous layer casing and the after layer for side tracking well.The open-hole liner and the previous layer casing can form a complete unite due to the good sealing and two-way hanging property.
2. After expanding the liner hanger, the open hole section and the casing pipe will be completely isolated so that the open hole section forms enclosed space.The fluid above the hanger cannot reach the formation,minimizing the pollution to the formation.
3. It can eliminate the damage to the previous casing by the conventional hanger and provide greater suspension force and higher reliability.
4. It has bigger inside diameter and enlarge the specification of the hanging liner.
5. It is a one-piece structure, which can effectively improve the whole strength of the hanger and make sure the other pipe runs smoothly.
6. Eliminate liner-top isolation packers (reduced complexity)
7. Reduce rig time through faster RIH
