ABSTRACT:
A well screen having slurry flow paths enclosed therein includes support rods extending in the axial direction of the screen disposed cylindrically at a predetermined interval in the circumferential direction of the screen, a wire wound on the outer periphery of said support rods so as to form slits of a predetermined width, one or more flow paths for gravel-containing slurry provided inside of the wire and extending in the axial direction of the screen, and openings for communicating the flow paths with the outside of the screen. Lowering and lifting of the screen through a wellbore can be made smoothly without interfering of the slurry flow paths with the wellbore and installation of the screen can thereby be facilitated.
