The base pipe is of 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. In the end, the filtration jacket with punched slot is welded onto the perforated base pipe through backup ring. In application, the formation sand can not easily enter the filtration jacket while the formation fluid can easily flow into screen through space between punched slots. So sand control is achieved.If needed, an extra outer protective shroud can be added outside the filtration jacket so to strengthen protection for the filtration jacket. 1. Slot with precise control The width of slot can range from 0.30~1.00mm with its width accuracy as ±0.05mm. So, it can match the formation sand in different particle size, and perfectly meet the requirement of sand control under the well. 2. With strong anti-corrosion ability Stainless steel filtration jacket with punched slot has strong resistance to acid, alkali, and salt. It is highly adaptive to H2S, CO2, and enables the space between slots not expanded because of corrosion in long-term use. 3. Perfect integral strength and strong anti-deformation ability, The internal part of filtration jacket is supported by base pipe and the outer protective shroud can be fixed outside the filtration jacket if necessary. The integral strength of base pipe with drilled holes is merely 2~3% less than standard casing or tubing. So it can withstand compression deformation from stratum with sufficient integral strength. Even if local deformation occurs, the gap of compressed part will not be enlarged. It has been proved to be highly reliable on sand control.
