The Wireline Tool String is necessary for the efficient surface control
during the running and pulling operations on slickline of sub surface
An assembly of wireline tools connected to the wireline is used to
deliver surface control impacts (jar action) either upwards or
downwards to manipulate devices within the well bore.
A standard set of wireline tool string typically consist of:
Wireline Socket (Rope Socket) for attaching the wireline to the tool
Wireline Stem (Sinker Bar) for adding weight to sink the tool in the
well bore against the well pressure and different gravity fluids
Wireline Jars (Spang Link Jar) for securing the hammering effect by
upward or downward movement.
Wireline Knuckle Joint for obtaining flexibility through the tool string.
Wireline running or pulling tool for running and retrieving devices
from the well bore.
All Wireline Tools are available with following:
- Sucker Rod Threads
- UN Threads
- Quick Lock Connection
Customer to choose the type of connection they want to use in
wireline tool string.
Sucker rod threads are machined on wireline tools asper API 11B.
These are economical cost wise.
UN threads are also machined on wireline tools and are
interchangeable with Sucker Rod Threads but are shorter in length.
These are also economical cost wise.
Quick Lock Connector as the name suggests is a quick connect and
quick disconnect connection, which is used in place of screwed
connection. It has many advantages over screwed connection:
- It is quarter turn connection.
- It is stronger than screwed connection. It has three impact load bearing surfaces in each direction, which make it safer for heavy and prolonged wireline operations.
- It is safer and simpler and can be released with a screwdriver.
