Wireline Lubricator with Integral Union

The Lubricator provides the downhole tool string with a pressure buffer zoneand a transition zone through which the instrument passes. According to theneeds of the site, multiple Lubricators can be connected in series.
The Integral Lubricator is a pressure containing cylinder used when performingwireline operations. Its purpose is to allow the Wireline Tool String to be raisedabove the wellhead prior to and after wireline operations, thereby enabling the wellhead valve to be opened and closed, allowing entry and exit from the wellbore. This type of Lubricator is usually recommended service in workingpressure10OOOPsi.
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. Thisinvolves a ported NP-1/2"sub between the Lubricatortube and the bottom Quick Union.
