Mainly used for gas drainage hole, also widely used for mining, geology exploration, hydroeceltric dam.
Casing pipe is used for protecting subsurface formations. It also
protects the bore hole form collapsing.
As an important part of the bore hole, casing has several important

Prevent bore hole collapse, the isolation of different formations
to prevent liquid convection between the formations and thus play a
role in controlling the drilling fluid and pressre while drilling.
