What is a sliding sleeve?

The

sliding sleeve generally concerns a number of ports to regulate different tanks inside the gas well or oil wells. These parts are generally installed during the final phases of the drilling process, sometimes called the phase of completing experts in the field. For example, most oil wells have a structure of production pipes to pull oil from a natural tank and pump into a storage device. Oil wells are generally drilled directly into a highly pressure -tied chamber, so that mechanical or hydraulic valves are necessary to check the material from the tank. Sliding sleeve is a device that allows this level of control. For example, the well may have two main production chambers, but the combined flow of both would burden the well of the well. In this case, the sliding sleeve of the CPC, with the installed sliding sleeve, is switched off, and at the same time it allows the other chamber to produce unlimited oil.

in most configuracThe sliding sleeve can be closed by a mechanical or hydraulic component controlled from the surface. The non -electrical cable used to physical change the components of the component inside the productive well is called wire and sliding sleeves is part of the connected to the wire and controlled from the surface. The "sliding" sliding housing concerns mechanical movement of the sliding ports when the handbag is activated.

Possible applications Configuration of sliding case in any well can change based on the type of well, manufacturing methods such as hydraulic breaking, well age and many other factors. There are also various sliding sleeve configurations, including open/close configurations that are typical of many holes. In TTOK it may usually begin or stop while the harmful configuration can be open to a variable diameter.

Many well intervention activities also benefit from sliding sleeves, as certain areas of the well may be narrowed while maintenance is performed in another area of ​​the well. For exampleThe well with two main chambers can still be productive in one chamber, while the other is primarily filled with water. The sliding sleeve would allow technicians to close the chamber well and draw oil from the second chamber.
