Mining Oil Sands Filtration
Metal foam has the characteristics of high strength and light weight, high porosity, strong corrosion resistance, and gradient distribution of pore size. Therefore, it has good filtering properties. It is widely used in industrial filtration and can be made into a variety of filters.
The principle is that the pores and cage structure of the metal foam material have the effect of retaining and trapping the solid particles contained in the fluid, so that the medium can be purified or separated. Metal foam filters can filter solid particles and other substances from liquid or gaseous media.
The shapes of commonly used filter elements are tubular, plate, sheet, disc, cup, etc.;
Foamed metal sand control pipes are used in Dagang Oilfield, Daqing Oilfield, Jilin Oilfield, Shengli Oilfield, etc. After downhole tests, the sand control effect is remarkable, especially for heavy sand oil wells. Compared with other types of oil production sand control pipes, it has high strength and corrosion resistance. Well, the life cycle is long.
