Product Description
A liner hanger is a device used in oil fields to hang liners within an oil well. So that oil can be pumped out of the well, a liner is used to create a vacuum. Liners can be installed mechanically or hydraulically, depending on the well. Setting a hanger is a crucial part of the process of "completion" which is the preparation of an oil well for drilling.
Mechanical liner hangers are designed to be used on vertical, onshore wells. These are durable machines capable of providing light to medium density liners. A mechanical liner hanger is lowered into a well and when it reaches its intended depth it attaches itself to the well’s cones, which are components that keep oil and dangerous gasses from escaping. Through using its mechanical parts, the liner hanger attaches itself to the cone, allowing for oil to pass through to the surface.
For offshore oil wells, onshore wells that are extremely deep, or high pressure high temperature (HPHT) wells, hydraulic liner hangers are used. These hang heavy liners and can be used horizontally as well as vertically. If the well is to be cemented, it is possible for the lining and cementing to be done simultaneously with hydraulic liner hangers, as this improves the stability of both the cement and the liner. As the name suggests, when the hydraulic liner hanger reaches its intended depth it attaches the liner to the cone by using
