A sand screen is a equipment use for filtration of sand from other materials, the most frequent application for sand screens is in oil drilling and production, especially in complication of the drills. Much of the world's crude oil and natural gas supplies are located deep underground, often in areas with desert-like conditions. Very large drills are used to bore below the surface of the earth in these areas to collect oil. A sand screen is often used to line the diameter of the bore, allowing oil and natural gases to filter through while keeping sand out of the bore hole. This helps prevent sand from getting into the drills, where it can slow production, or even render the drilling equipment unusable.

Sand control screens are offen made from stainless steel mesh, which helps the screen hold up under harsh conditions. Now Lyrun developed a new material as porous metal foam filter to replace the stainles steel layers in traditional products of sand screen.

Compared to stainless mesh layers filter, the porous metal foam filter use for oil production has following advantages:

1. Better corrosion resitance, as a harsh condition in the drills, stainless steel is become flabby easily, but for a special porous three-dimensional structure.
2. Better blocking prevent performance.
3. Good plasticity, processing to many shape to suit the bore.
