Punch-wound screen tubes are composite screen tubes with a wire-wound screen sleeve and a punched screen sleeve mounted sequentially on the outside of the base tube.

Technical characteristics:

• The outer punched seam screen sleeve can protect the inner wire-wound screen sleeve, and it can have the function of filtration itself.

• has set up the punching seam screen sleeve, and the silk screen sleeve is welded with the support ring as a whole, which has good protection and support function, in which the outer diameter of the support ring is larger than the outer diameter of the screen tube, so that the screen tube can be effectively protected from injury during the process of descending the well.

• Punching slit screen sleeve with bridge-type aperture, the width of punching slit can reach 0.25-0.5mm, which changes the direct impact of liquid flow on the stainless steel mesh filtration layer, and effectively protects the layer of wire-wound screen sleeve.

• is made of 304 stainless steel material, the whole has the remarkable features of high strength, corrosion resistance and high temperature resistance, especially adapted to the thick oil hot recovery of horizontal wells and large inclination wells.
