J55 Laser Perforated Pipe Base Screen with 304L Wedge Wire Jacket – Sand Control Screen for Oil Well & Geothermal Well Filtration

 
 
1. Product Description
 
This description covers a completed production batch of large-diameter dual-layer screens made for a specific client. Each unit begins with a J55 carbon steel base pipe that is laser-perforated along its full length, then wrapped with a 304L stainless steel wire screen jacket welded to the pipe body, and finished at both ends with long round threads (LTC). The batch has passed final inspection and is ready for shipment.
 

 
 
2. Structure Up Close
 
- Base pipe: J55 carbon steel, laser-drilled holes with clean, burr-free edges and consistent spacing, keeping pressure integrity while opening a large flow path.
- Jacket: 304L stainless steel V-shaped profile wire, continuously resistance-welded onto longitudinal support rods for uniform slots and a self-cleaning surface.
- Bond: jacket and base pipe are welded into one rigid assembly, so both layers share downhole load.
- Ends: long round thread (LTC) on both ends, with thread protectors fitted for transport.
 
 
3. Why This Combination Works
 
Laser perforation offers a much larger open flow area than drilled or slotted pipe, lowering inflow resistance and evening out flow along the screen. The 304L jacket handles filtration: its V-profile slots hold back formation sand, and the smooth wedge surface sheds fines during backflush. Carbon steel inside balances strength and cost; stainless outside carries the corrosion duty. The result is a screen that is strong, economical to run and easy to clean.

5. Running And Maintenance Notes
 
- Lift with slings; never hoist by the thread ends.
- Fit centralizers on the string to limit wall contact while running.
- Backflush at planned intervals; inspect slot condition after each pull.
 
 
 
6. Made By OASIS
 
Good pipes, made by OASIS. Each screen leaving our workshop carries the same promise: J55 and 304L material certificates on file, laser hole inspection, slot gauge verification, weld examination and a final dimension and pressure check. The batch is wrapped in bubble film, thread ends capped, and crated for damage-free delivery.
 

 
 
7. FAQ
 
Q: Can the hole size and pattern be customized?
A: Yes, laser hole diameter, spacing and pattern follow the customer drawing.
 
Q: Why combine carbon steel with a stainless jacket?
A: The carbon steel base carries strength and cost efficiency, while the 304L jacket provides the corrosion resistance and filtration performance.
 
Q: What thread types are offered?
A: Long round thread (LTC) is standard for this batch, with BTC, STC, EUE or NUE available on request.
