Description
The Hydraulic Liner Hanger is a downhole completion tool engineered to secure and support a liner string inside a previously installed casing in oil and gas wells. It uses a hydraulic setting mechanism that allows the hanger slips to be set by applying pressure down the liner string, offering reliable performance in a variety of well conditions. Hydraulic liners are especially suited for deeper, deviated, or horizontal wells where mechanical setting may be challenging.
Product Overview
A liner hanger is a critical component in well completion that provides mechanical anchor and support for a liner string once it is run to depth. Unlike full casing strings that extend back to the surface, liners reduce material costs and rig time while maintaining well integrity. Hydraulic liner hangers activate the slips using downhole pressure, making them ideal for wells where string manipulation is difficult or impractical.
The Hydraulic Liner Hanger from Shangshan Petro features high-strength construction, large slips for hanging moderate to long liners, and a pressure-activated setting mechanism that improves deployment reliability in complex well paths.
Key Features & Advantages
-
Hydraulic Setting Mechanism
The hanger slips are set by applying hydraulic pressure through the liner string, eliminating the need for drill string manipulation in deep or deviated wells. -
Large Slips for Secure Hanger Support
Designed with large slips capable of supporting moderate to long liner strings with confidence. -
Suitable for Deviated and Horizontal Wells
Well-suited to challenging well trajectories where mechanical set hangers struggle to engage. -
High Mechanical Strength
Constructed for reliable performance under load and sustained downhole conditions. -
Easy Running Tool Separation
After setting, adding 5–8 tons of surface pressure safely releases the setting tool by unscrewing.

Applications
The Hydraulic Liner Hanger is widely used in:
-
Oil & gas well completion where liners are deployed
-
Deep and deviated wells requiring hydraulic set hangers
-
Wells where mechanical hanger setting is difficult
-
Completion operations demanding reliable hanger support
-
Horizontal well sections where liner stability is critical
Hydraulic liner hangers support liner deployment, stabilize the casing liner, and facilitate cementing by providing a reliable anchor point.
Frequently Asked Questions
Q1: What is a hydraulic liner hanger?
A hydraulic liner hanger is a liner anchor device that sets its slips using downhole fluid pressure, allowing reliable liner support in wells where mechanical manipulation is difficult.
Q2: Where are hydraulic liner hangers typically used?
They are commonly used in deep, deviated, or horizontal wells where mechanical liner hangers may be hard to set.
Q3: How is the hanger released from the setting tool?
The setting tool can be released from the hanger by applying surface pressure (e.g., 5–8 tons), enabling unscrewing and separation.
Q4: What are the main advantages of hydraulic hanger systems?
Hydraulic hangers provide remote activation with minimal string manipulation, and they can be set reliably in complex wellbore conditions.
