The wire-wrapped screen consists of perforated pipe, outer jacket ，end ring and centralizer. Key-stone or house shape wires are simultaneously wrapped and welded to form uniform slots. The jacket is then placed over perforated pipe and welded to each end. The JEONSURE wire-wrapped screen’s strength, high quality and precise slot control make it an excellent choice for deep, vertical wells as well as horizontal wells.

Ⅰ、Wire-wrapped Screen Characteristics 

 ● Key-stone shaped slot pattern, low risk to plugging, easy to clean;

 ●Superior resistant to corrosion and long lifespan in applications;

 ●Optimized design for perforation, all welded structure, high mechanical strength which is competitive with casing of the same size;

 ●Minimum slot opening: 0.1mm, which can satisfy the most of well-completion requirements.

 ●High flow area;

 ●The technical is mature, good adaptability.

Ⅱ、Applications
Gravel-packing in cased-hole completions of vertical wells, directional wells, horizontal wells, multi-lateral wells and open-hole completions.

Ⅲ、Filter Principle

Wire-wrapped screen provide effective sand control for nominal gravel packing application. The  slot is designed to stop the gravel and the sand from the earth is then stopped by the holes  formed by the gravel.
