Product Description

Stainless Steel Wedge Wire Pipe Based Well Screen for deep well
 
Pipe Based Well Screen


Slip on wedge wire screen
Application:
Slip on wedge wire screens are often applied in sand control applications where screen durability is critical. It is used in highly deviated and horizontal wells, in cased hole, open hole, fracturing and gravel pack completions.
Wedge wire screen is designed with the high mechanical capacity to withstand thermal, torque, compression and pressure loads.

1. Heavy oil, sand oil, SAGD, CBM, bitumen, thermal
2. Water injection 
3. Horizontal, vertical , deviated oil and gas, and water wells 
4. Stand-alone operations, cased hole, open hole environments and horizontal completions
5. Horizontals with high angle



Pipe based well screens consist of base pipe. all-welded wedge wire screen and supporting rod.
The base pipe is perforated or slotted API casing pipe, the base pipe can be stainless steel or carbon steel API 5CT casing. The all-welded wedge wire screens are welded together with base pipe by supporting rod.




The pipe based screen has two sets of openings, the outer continuous slot and the holes drilled in the pipe base. The open area of the pipe base generally is less than that of the outer screen open area, and the inner pipe has a maximum open area of 10%. Hydraulic performance of the assembly depends on the open area in the pipe base, which usually is made of steel and has an outer screen made of stainless steel. This bimetal contact typically supports some electrolytic action and causes corrosion of the steel pipe. One way to prevent corrosion is to use pipe and screen made of the same metal- the cost might be somewhat higher, but the product is more durable.

Features of pipe based well screens
 
1. Higher filtering accuracy: all-welded wedge wire screens as screen jacket with vee opening design makes the filtering accuracy higher, which can control sand better.
2. Excellent strength and resistance to deformation: The base pipe inside, the outside can be protected with the protection jacket added according to requirements, the integrated strength of the perforated base pipe only decreases 2~3% compared with the standard casing/oil tubing, so the pipe based well screens have enough integrated strength to resist to the pressure caused by strata. Even if some part of the well screens deformed, the slot of this part will not be widened, which makes higher sand control reliability.
3. More choice: the material of screen jacket can be stainless steel or carbon steel, the material can be chosen as per customers' requirement.
4. The smaller slot will increase the oil and gas production. 
5.The excellent technique makes the mass production with high efficiency and low cost available.
