The casing head is a kind of part of connecting casings and wellheads.It is used to support the weight of technical casing and oil string and seal the annular space between the casing,which provides a transition joint for the installation of the tubing head.The two-side-outlet design allows the casing head to supply cement,monitor and control well's sinking,and inject balance liquids etc.
