the following example is for you reference.


1.Brief Introduction:

  

WELL SCREEN without BASE PIPE

DESCRIPTION

Well screen without base pipe is manufactured with spiral winding of profiled wire onto support rods connected by welding at each point of intersection.this type of screen has no base perforated pipe,while not conceding on the strength characteristics of slip-on screens with base pipe.

the filtration degree is determined by the slot size(from 100microns to 2000 microns).

Well screen without the base pipe are available in different sizes.

Underground gas storage

APPLICATION

Completion of Oil&Gas and Water wells: casing,open hole,open hole with gravel pack

Vertical,directional and horizontal wells

Sidetracking

 

2.Techincal parameters:

  

BENEFITS

Ultrahigh strength and rigidity

Provide laminar flow of filtered fluid through the filer

Tight slot tolerance (+/- 15 microns)

Screen diameter range of 70mm to 1000mm

Providing minimum hydraulic resistance

Easy backwashing

the triangular profile wire greatly reduces the risk of screen clogging

Filter elements are made of stainless steel AISI 304,AISI316,etc.

 

3.Performance features:

1. Screens with high open area are more suitable for the construction of high-quality water wells, oil wells and gas wells. 
2. Low cost operation Screens with high open area shall favor groundwater infiltration. Abundant water shall reduce the water level'S down, thus to save energy consumption.
3. Reduce the abrasion of the pump 
under the same condition, high open area can make the speed of groundwater'S entering into the screen much slower than any other filtration apparatus, which will avoid sands entering into screen because of high pressure, thus reduce the abrasion of the pump.
4. Extend the life span of wells 
Comparatively, groundwater'S entering into screen with higher open area is much easier than the entering into lower open area screen. the slow water flow shall extend the life span of wells.
