Description
High Quality Chinese Facotry Lancing Composite Sand Prevention Tube
(1)Multilayer stainless steel tight mesh grid composite filtering layers, with high sand prevention reliability.
(2)Strong extrusion deformation and bending deformation resistance, unchangeable sand prevention in 40% radial deformation, meet operating requirements of horizontal wel
(3)Larger filtering area, low flow resistance, and high output.
(4)Accurate and controlled size of filtration hole (error less than 5mm), stable and undeformed filtration hole.
(5)Uniform filtration holes, high permeability, strong blocking resistance, 2-3 times of blocking cycle than that common screen pipe, facilitating backwashing.
(6)Standard sleeve or oil tube as base tube, filter layer made of highquality stainless steel with strong corrosion resistance to CO2, CL- and H2S, and adaptability to acidizing treatment. (7)Small external diameter, light weight, facilitating pushing in place in long-distance horizontal section.
