All-Welded (AW) Wire-Wrapped Screen
Introduction
Unsurpassed in design, construction and performance, Kingwell All-Welded (AW) wire wrapped screen provides field-proven sand control with a long history of reliability. The wire-wrapped screen features a keystone shaped wrap wire on round rib wires for improved plugging resistance. Advantages over conventional screens are significant.
Extra strength
The AW screen combines high strength and superior corrosion resistance for unsurpassed durability during
installation or retrieval. The stainless steel wrap wire—firmly welded to every rib wire—is designed not to shift or unwind in the unlikely event should it be damaged downhole.
Large inlet area
The AW screen has a much larger inlet area than conventional wire-wrapped screens. No solder strips, weld beads or lugs are present to block flow. Plus, a larger inlet area results
in lower entrance velocity for produced fluids, reducing the potential for screen erosion.
Filtration assurance
With precise gauge control for reliability, gauge spacing of the AW screen is permanent. Weld strength and wire
orientation are controlled to ensure the gauge required is the gauge delivered down hole.
Filter Construction
Round wires form the ribs, while the diameter and number are specified by the strength required and size of
screen. Keystone-shaped wire is used for the wrap wires, which are helically wrapped around the preset vertical rib wires. Each
point of contact is welded using a proprietary Halliburton procedure. Wrapping is accurately controlled—resulting in a uniform, precise gauge. The keystone shape of the wrap wire forms "V" shaped openings between wraps. This shape opening provides self-cleaning action and greatly reduces flow friction. Smaller particles can easily pass through the continuous slot
while larger ones are held out without inhibiting the total inlet area.
Features & Benefits
Wire Wrapped Screen is a simple-structure, dependable and effective sand control screen, A robust design, manufactured using leading-edge technology, provides the client with a reliable filter system for standalone screen or gravel pack applications
, advantages as follows:
1 Helically wrapped and welded by Specially designed trigonal wire, trapezoidal cross-section, anti-clogging;
2 Keystone slot, never plugging in the slot;
3 Large flow area, about tenfold to slotted screen with identical slot size;
4 SST or alloy material provides high corrosion resistance.
