Quick Test Sub 5K Wireline Pressure Control Equipment
The Quick Test Sub is designed to save drilling time while pressure testing the lubricator device before exposing it to well pressure. When wiring is required multiple times, the lubricator must be tested every time the bottom connection is disconnected, which wastes a lot of time. After the first pressure test of the entire pipe string, a quick pressure test pip can be used for subsequent pressure tests to verify the integrity of the joint disconnection, instead of testing the entire lubricator assembly. This is done by connecting a small hand pump to and testing two O-ring seals from the outside. The quick pressure test puppet is installed above or below the BOP and becomes a joint
Disconnect every time to insert and retrieve tools from the well
II. Design Features
The Quick 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 Quick 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.
The Quick Test Sub is available for all diameters, pressure ratings and service with suitable quick unions for wireline operations, or flanged for coiled tubing and geothermal applications. The Quick Test Sub may be used as a stand-alone unit, which is inserted into lubricator riser assembly, or as an integral part of the BOP where reduced height is advantageous The pressure integrity test is carried out by means of a hand operated hydraulic pump fitted with a certified pressure-monitoring gauge. If required the hand pump can be supplied with a programmable electronic pressure/time recording gauge assembly for test result verification. Filling of the test chamber, with a volume approximately 5 cubic inches, and achieving required test pressure normally takes less than a minute. It is recommended that test pressure be held 10 minutes to ensure that no losses have occurred. Bleed down of the test fluid/pressure is compulsory and can be carried out at the bleed down valve on the electronic pressure recorder or hydraulic hand pump.
IV. Use method
1. Before loading the upper cylinder into the lower cylinder, the two sealing rings on the upper cylinder and the sealing holes of the lower cylinder should be evenly coated with sealing grease.
2. Align the upper cylinder with the sealing hole of the lower cylinder and carefully assemble it. Do not damage the sealing surface and O-ring during assembly.
3. Use a hook wrench to tighten the union nut.
4. Connect the pressure pipeline with the quick connector.
5. Complete the abo:ve steps and immediately start the pressure test.
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.
