Pipe Based Well Screen,Sand Control Screen:
1. Pipe based well screen also be called maltilayer screen,sand control screen.
2. Jacket Screen Material: 201 304 304L 316 316L
3. Another name: Pipe base screen
4. Screen jacket: Johnson type screen
5. Base pipe: Perforated pipe
6. Connection type: STC, LTC,BTC threaded couplings
7. Bubble bag, wooden pieces wrapped the Johnson screens
Pipe based well screen pipes are used for oil and water exploiting.
Characteristics:
Pipe based well screen consists of two screens or multilayer screens
Perforated pipe inside ,with perforations wrapped by the outside Johnson type screen
The screen jacket and base pipe are welded together with a length of coupling.
The base pipe can be made of seamless pipe or welded pipe, and more often, casing pipes.
ID of Johnson type screen equals OD of the perforated pipe.
Pipe based well screen combines stainless steel or carbon steel casing with continuous slot well screens for additional strength in deep well applications. The pipe strength allows smaller wrap wires to be used, allowing for greater open area.
Features:
Higher Collapse resistance.
Higher Load Strength.
Easily controlled open area for regulated flow rates.
Threaded Fittings in any specifications required.
Base pipes can be manufactured using stainless steel grades series or API 5CT carbon steel casing.
The pipe based well screens are recommended when high collapse resistance is required and when the screens’ length generates a high longitudinal constraint. The pipe strength allows smaller wrap wires to be used, yielding greater open area.
OASIS oil tools use prime pipe, thoroughly cleaned and de-burred after perforating.
Diameters for pipe based well screens range from in. 1.5 inch to 18 inch.
