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