Popular Name： Lubricator / Wireline Lubricator / Integral Lubricator
The Lubricator provides the downhole tool string with a pressure buffer zone and a transition zone through which the instrument passes. According to the needs of the site, multiple Lubricators can be connected in series.
The Integral Lubricator is a pressure containing cylinder used when performing wireline operations. Its purpose is to allow the Wireline Tool String to be raised above the wellhead prior to and after wireline operations, thereby enabling the wellhead valve to be opened and closed, allowing entry and exit from the well bore. This type of Lubricator is usually recommended service in working pressure≧10000Psi.
Generally, it requires the total length of Lubricator sections at least 1000 mm longer than downhole string tool.
An optional Bleed-off Port may be incorporated into the lubricator assembly. This involves a ported NPT-1/2” sub between the Lubricator tube and the bottom Quick Union.
