1.High permeability, larger area of flow and production rate is high
2.Anti- acid and alkaline, anti-high temperature
3.low

Premium screen is the new generation of sand control screen researched and manufactured by our company; it has the characteristic of simple in construction,easy in operation, high reliability, high intensity and high permeability.

 

The Structure of premium Screen

1.Premium screen mainly consists of perforated base pipe and filter jacket.  The jacket consists of inner shroud, inner drainage mesh, inner mesh media,  middle drainage mesh, outer mesh media as well as external stainless steel shroud.

2.Internal drainage mesh wrapped on the inner shroud, and provides even distribution of flow, it also has the function to support filter media. 

3.Inner/outer mesh media is able to meet the requirements of sand control for all sand with different diameters.

4. Middle drainage mesh has the function to separate two layers of filter media, ensuring the accuracy of filtering. 

5. It also has the role to provide even distribution of flow for the media.
6.Stainless steel shroud has the role to protect media layers and drainage mesh when going into well or bear  the negative pressure.

 

Product Characteristics 1.Multi-layer 316L stainless steel filter media has been adopted, with high reliability and anti-damaging  ability in sand control. 2.High permeability, larger area of flow and production rate is high.  3.Small outer diameter, light weight, easy to push along the long horizontal section.  4.Anti- acid and alkaline, anti-high temperature, long life for use.

5.Simple construction, easy for operation, it benefits to lower the construction expense, and raise the rate of success in construction. 6.Premium Screen samples deformed to 75% and 40%of original diameter with virtually no increase in sand production.

Product Application    Premium screen is mainly suitable for barefoot completions especially for oriented well and horizontal well.    The particularity of well opening of the horizontal well causes a low rate of success of the traditional gravel packing completion,

 

Feature of screen and principle of filtration
The multi-layer structure has been used; the filter media is made by 316L stainless steel wire by use of special technology. The filtration accuracy and rate of hole-making can be controlled via controlling of wire diameter and us mesh to be used. 

1.It’s interwoven by use of 316L stainless steel wire, with high intensity,    strong ability to resist breakage.

2.High accuracy of filtration, high reliability in sand control. 
3.High permeability. 

4.Acid and alkaline resistance, high temperature resistance.
5. Easy to reverse wash and long service life.
