Sand Filter Screen Element - Multi Layer Screen Filter Cartridge Pipe for Oil and Gas Wells

Multi layer sand filter screen is a kind of Compound Grading Sand Control Screen designed for oil and gas wells to prevent sand from wellbore during production. It features a multi-layered structure that combines various grades of filter mesh, providing precise sand retention while ensuring optimal fluid flow.

• Multi layer sand control screen offers following 5 features:
• Filter fineness for effective sand control of a wide spectrum of formation sands;
• Consistent mesh and pores diffusion assuring effective sand control under high operating pressures in oil wells;
• High porosity leads to lower pressure drops, and increased service life;
• Grade sand control tech by combining surface filtration with deep filtration;
• Comination of woven wire mesh with perforated metal ensures robust structure, fine filtration and high strength.
