Abstract
A well screen is disclosed for positioning in a well bore to screen solid particles from the fluid produced by the well including a perforated base pipe having threaded connections for connecting the base pipe into a pipe string and a wire screen surrounding the perforations of the base pipe, a tubular shroud covers the screen and provides an annulus between the shroud and the screen, the shroud having a plurality of round holes through which well fluid can flow into the annulus, a plurality of arcuate straps located in the annulus with the ends of each strap attached to the shroud on opposite sides of one of the holes in the shroud to cause the well fluid flowing through the holes to swirl as it passes through the holes and to flow laterally from each side of the straps into the annulus between the shroud and the screen.
