Description
-
The Mechanical Liner Hanger is a liner suspension tool used in oil and gas well completion to hang and support the liner string securely inside the previously installed casing. Mechanical liner hangers are set by physically engaging slips and cones against the casing wall, providing a simple and reliable method to suspend liners in conventional well conditions.
This model is an economical choice for applications that do not require heavy-duty hanger systems but still need dependable liner support and easy running tool release.
Product Overview
In well construction, a liner hanger is installed at the top of a liner string to connect and secure it inside the previous casing string. It enables the liner to be suspended at the desired depth without running casing back to surface, optimizing both cost and rig time.
Mechanical liner hangers rely on mechanical engagement — such as slips and a J-cage mechanism — to set the hanger by rotation or weight application on the liner string, providing a straightforward and field-proven method of hanger setting.
This Mechanical Liner Hanger from Shangshan Petro is designed to be efficient, reliable, and easy to operate, making it suitable for many typical well environments where mechanical setting is appropriate.
Key Features & Advantages
-
Mechanical Setting Mechanism
Uses a simple J-cage or mechanical slip system that can be set by weight or rotation on the liner string, eliminating the need for complex pressure activation. -
Economical Solution
Offers a cost-effective hanger system for applications not requiring high-capacity or specialized hangers. -
Cone-Grip Slips Available
Optional cone-grip slips help prevent floating of very short or light liners during cementing, improving operational stability. -
Easy Running Tool Release
After setting, the setting tool can be separated from the liner hanger by applying 5–8 tons of surface pressure, enabling unscrewing and retrieval. -
Field-Proven Simplicity
The mechanical engagement design has fewer moving parts compared with hydraulic systems, simplifying maintenance and reducing setup complexity.

Applications
The Mechanical Liner Hanger is used for:
-
Hanging liners in oil and gas well completion
-
Conventional well environments where mechanical setting is suitable
-
Hanging moderate liner lengths without hydraulic activation
-
Projects requiring simple and cost-efficient liner support
Mechanical liner hangers are widely used where liner suspension does not require complex setting mechanisms and where rig operations can apply weight or rotation for setting.
Frequently Asked Questions
Q1: What is a mechanical liner hanger?
A mechanical liner hanger is a liner suspension tool that sets its slips through mechanical engagement, such as weight or rotation, to anchor the liner to the casing.Q2: How does a mechanical set differ from a hydraulic set?
Mechanical set liners use physical forces for hanger engagement, whereas hydraulic systems activate slips using fluid pressure — hydraulic hangers are often used in deep or deviated wells where mechanical manipulation is difficult.Q3: What are cone-grip slips used for?
Cone-grip slips help prevent very short or light liners from floating during cementing by providing improved slip engagement with the casing.Q4: How is the setting tool removed after hanger setting?
The setting tool can be released by applying a small surface pressure (e.g., 5–8 tons) to unscrew and separate from the liner hanger. -
