LINER HANGER, MECHANICAL SET , OILFIELD TOOLS, WELL CONSTRUCTION Liner hanger Liner Hanger is similar to casing, is a tool system that is used to
hang a liner in a production well.But it is not run through the full depth of the well, as casing is,
A liner hanger allows the liner (casing below the liner hanger) to
be suspended in the previous casing string to reduce material cost
and provide completion solution options. A seal is required at the
top of the liner hanger to prevent transfer of fluid or pressures
from either direction.
Liner Hanger belongs to Cementing or Drlling? Cementing itself is
a process in the drilling process. The liner hanger is a cementing
tool used in the cementing process.Many layers of casing are
dropped during the drilling process. The liner is a type of
casing. The liner hanger pipe is generally used as the production
casing at the bottom. The connection between the hanger pipe and
the upper casing depends on the tail pipe hanger. After the
casing or sieve pipe is installed, cement injection is required to
complete the cementing.
Liner hanger systems could be mechanical or hydraulic, premium or
standard, rotating or non-rotating, conventional or expandable and
pocket slip.
LINER HANGER MACHANICAL-SET
The mechanical-set liner hangers are inexpensive,
light-to-medium-duty hangers;
They are available in right-and-left-hand set models,depending on
the type of setting tool to be used. Multi-cone design maximizes
bypass area for run-in and cementing.
ADVANTAGES
1-Economical choice for cost-sensitive applications not requiring
2- Multi-cone design provides maximum bypass area
3- Single slot J-cage available for right-or-left -hand setting
4-Cone-grip slips available to prevent floating of very short,
light liner
5- Availble in sour gas well using special material
