The perforated 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.
