Key Features
  • Slots are made on base pipes with a large ID/OD ratio.
  • High mechanical strength, high flexibility to allow adequate bending, which makes the pipes applicable in complicated well conditions. Also used in open-hole horizontal well completion for sand control.
  • Low manufacturing and down hole installation costs.
  • Open hole area: 2%-6%.
  • Base pipe: J55, N80, P110, etc.
  • A continuous slot opening which significantly increases the available open area, thus providing greater access to the water bearing zone.
  • High oil production rate due to a large filter area and low flow resistance.
  • Uniform and efficient well development due to a continuous slot opening.
  • Anti-acid, anti-alkali, and anti-corrosion. Cracks won't become larger because of corrosion.
  • Easy backwashing, durable, safe and reliable use and cost effective.

Packing
Each tube is wrapped in a plastic membrane or according to customers' demand.
Slot Types 
Straight Mill Slotting
The slots of this slot type are of equal width throughout the wall of the casing, and therefore are more susceptible to clogging by sand from the formation than the Keystone slot described below. The slots are normally cleaned by hydro washing.
Keystone / Undercut Slotting
Trapezoidal seam design making the outer surface of the slot wider than the inner surface, thus greatly reducing the chance of slot clogging clogging. Typically, the trapezoidal slot angle is designed to be 6°.
Slot patterns
Slots are either arranged in parallel or in an offset pattern. The offset pattern offers a better stability.
Note: Please also take a look at our high quality sand screens.
