Quick Union Wireline Lubricator Hydraulic Pressure Control

Quick Union Wireline Lubricator Hydraulic Pressure Control

I. Introduction
Wireline Lubricator Wireline Pressure Control is a tube which with quick union and can stand high pressure, it’s used to accommodate wireline toolstring. Wireline Lubricator Wireline Pressure Control bottom end is connected with blow our preventor, upper end is connected with hydraulic stuffing box and grease injection system. Usually lubricator length is 8ft, sometimes also available 4ft and 7ft, it’s decided by the downhole tools length when operation. There are two types: Upper and lower lubricator.Upper lubricator is basic toolstring such as rope socket, stem, jar, etc;
Lower lubricator is for accommodate downhole devices, it’s with bleed off port. Install the pressure jointon it and then install the pressure release valve to read the well pressure and release it.
