Slotted Liner/slotted water well casing pipe

The slotted liner is mainly used to the water and oil reservation layer without much sand.Its  function is to prevent  rock bits dropping  into the well bore.The working principle is allowing the certain size and coming through the surface with crude oil but keeping the bigger size sand being stopped outside to form sand bridge ,and thereby achievement the anti-sand purpose.This type of product is commonly used to sand rock and catbonate reservoir,and especially useable for horizontal wells.

Characteristics

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 sand’s 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.
