What is a lubricator valve?
1. n. [Well Workover and Intervention, Well Completions] The topmost valve on a Christmas tree that provides vertical access to the wellbore.
How does a lubricator valve work?
The lubricator valve for the subsea test tree is a surface-operated hydraulic valve that is run from one or two joints below the flowhead. In event of control line pressure failure, the valve will remain in the last position, open or closed, that it was placed in before the pressure loss occurred.
What is the meaning of lubricator?
Definition of ‘lubricator’ 1. a person or thing that lubricates. 2. a device for applying lubricant.
What is the function of lubricator in FRL unit?
A lubricator adds controlled quantities of tool oil into a compressed air system to reduce the friction of moving components. Most air tools, cylinders, valves, air motors, and other air-driven equipment require lubrication to extend their useful life.
What does the lubricator do?
What is the difference between wireline and slickline?
While a slickline is a thin cable introduced into a well to deliver and retrieve tools downhole, a wireline is an electrical cable used to lower tools into and transmit data about the conditions of the wellbore. Usually consisting of braided cables, wirelines are used to perform wireline logging, as well.
What is the name of lubrication?
Many different substances can be used to lubricate a surface. Oil and grease are the most common. Grease is composed of oil and a thickening agent to obtain its consistency, while the oil is what actually lubricates. Oils can be synthetic, vegetable or mineral-based as well as a combination of these.
What is the purpose of a lubricator?
A lubricator for a pneumatic system provides lubrication to internal working parts of pneumatic tools and components, including actuating cylinders, valves and motors. The device injects a stream of oil into the airline, ensuring they perform at the optimum level at all times.
How should air lubrication be mounted?
Where should a lubricator be installed?
- Oil-mist lubricator should be installed within 5 meters of the application.
- Micro-fog type lubricator should be installed within 30 meters of the application.
- Always install downstream from a filter and a regulator.
What is slick lining?
Slickline refers to a single strand wire which is used to run a variety of tools down into the wellbore for several purposes. It is used during well drilling operations in the oil and gas industry. In general, it can also describe a niche of the industry that involves using a slickline truck or doing a slickline job.
What is a lubricator and why do I need one?
As a fluid power consultant, one of the most common questions I get is, “What is a lubricator, and why do I need one?” A lubricator is a pneumatic component that injects a fine mist of oil into the air to assist in the movement of directional valves, cylinders, motors and other pneumatic tools.
What are the parts of the lubricator Assembly?
The top of the lubricator assembly includes a high-pressure grease-injection section and sealing elements. The lubricator is installed on top of the tree and tested, the tools placed in the lubricator and the lubricator pressurized to wellbore pressure.
How does a pneumatic lubricator work?
As you can see, the lubricator preforms many unique rolls in the system and is a vital part of any pneumatic circuit. The lubricator does this through the use of the Venturi effect. Simply put, the Venturi effect is when air flow is restricted trough an orifice and ported into a separate chamber.
What is the venturi effect in lubricants?
Simply put, the Venturi effect is when air flow is restricted trough an orifice and ported into a separate chamber. This orifice, often called a Venturi Throat, causes an increase in air pressure, which is what forces air into the lubricator bowl.
