Well screen with frame-core structure


  • Completion of Oil&Gas and Water wells: casing, open hole, open hole with gravel pack
  • Vertical, obliquely above, horizontal wells
  • Sidetracking


  • Ultrahigh strength and rigidity
  • Provide laminar flow of filtered fluid through the filter
  • Tight slot tolerance (+ / - 15 microns)
  • Screen diameter range of 70mm to 1000 mm
  • 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, AISI 316, etc


Well screen with frame-core structure are manufactured by the method of spiral winding of profiled wire on the support elements of different cross-section, connected by contact welding at each point of their intersection.

This type of well screens does not have a base tube, while not yielding to the main strength characteristics of well screens with direct winding, it can be installed on a perforated pipe.

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

Well screen with frame-core structure can be manufactured of different sizes.
