Its funcation of well screen and oil withdrawing is preventing rock bits dropping into the well bore.The working principle is allowing the certain size to pass the surface with crude oil but stopping the bigger size sand outside to form sand bridge,and thereby achieving the anti-sand purpose.This type of products is commonly used in sand rock and catbonate reservoir,and especially useful for horizontal wells.
