Screen mainly consists of perforated base pipe,stainless steel filtration jacket with punched slot,and backup ring.The base pipe isof API casing or API tubing with many drilled holes.The filtration jacket with punched slot is made of high quality stainless steel,and the spatial slot in high dense array over it is achieved by digital control precise punching.The filtration jacket is welded onto the perforated base pipe through backup ring.If need,an extra outer protective shroud can be added outside the filtration jacket to strengthen protection for the filtration jacket.

Its precise control slot range from 0.02~1.00mm with its width accuracy as 0.02mm.So it can match the formation sand in different particle size,and perfectly meet the requirement of sand control under the well.The stainless steel filtration jacket with punched slot has strong resistance to acid,alkaliand salt.It is highly adaptive to H2S,CO2 and enables the space between slots not expanded because of corrosion in long-term use.The internal part of filtration jacket is supported by base pipe and the outer protective shroud outside it.So it can withstand compression deformation from stratum with sufficient integral strength.Even if local deformationoccurs,the gap of compressed part will not be enlarged.
