Wireline In-Situ Test Sub
Cast aluminum
China Baoji
Wireline & Slickline
Standard
The Wireline In-Situ Test Sub allows for only the joint that was broken to be tested, without filling the whole lubricator system, saving a substantial amount of time and large volumes of expensive test fluid, as well as alleviating the problems associated with dumping test fluids into the well.
As an added advantage, the In-situ Pressure .The Wireline In-Situ Test Sub allows for the lubricator system to be pressure tested whilst pressure sensitive equipment (such as perforating guns)are in the lubricator.During Wireline operations it is necessary to break the quick union between the lower lubricator and the BOP to remove the tools within. When this joint is reconnected it is normal practice to fill and pressure test the entire lubricator system prior to opening the wellhead valve.
The Wireline In-Situ Test Sub is fitted between the lower lubricator and the BOP, and becomes the joint that is broken out between wireline runs. It looks and operates like any other quick union, but has two “O” ring seals instead of one. The pressure testing takes place between these two seals and effectively confirms the integrity of both. The upper-most of the two seals is of slightly larger diameter than the lower, facilitating easy make/break of the connection. As a safety precaution, the Wireline In-Situ Test Sub 's connection is designed so that it cannot be inadvertently connected to any other known quick union Testing would normally be done to the working pressure of the lubricator system, but each sub is designed so that it can be tested to the full test pressure of the system.
After using this product every time, check whether the thread, Sealing surface and O-ring are damaged. If everything is normal, apply lubricating grease to the thread and sealing ring, and take protective wire for storage. If any damage is found to the O-ring or sealing surface, the manufacturer shall be contacted in time for repair and replacement.
