liner hanger hydraulic-set
The hydraulic-set liner hanger is set hydraulically by applied pressure through the run-in string, and is designed to support medium to heavy liner loads. The hanger is widely used in deep and high deviated wells, where actuation of mechanical-setmay be not preferred. A setting ball is dropped and/or circulated to a ball seat in the landing collar or running string. Differential pressure acts on the hydraulic cylinder, moving slips up the cones to the set position.
Advantages and Features:
1- Hanger sets with applied hydraulic pressure
2- No pipe rotation required to set hanger
3- Large slip area capable hanging moderate to long liners
4- Multi-cone design provides ensure high-pressure or temperature integrity
5- Ever hydraulic settinbg mechanism is factory tested to ensure downhole reliability.
6- Available in sour gas well using special material
