Casing head

The casing head is a component that connects the casing and various wellhead devices. It is used to support the gravity of technical casing and oil layer casing, seal the annular space between each layer of casing, and provide transitional connections for the installation of blowout preventers, tubing heads, Christmas trees and other upper wellhead devices. One side port can be used for supplementary squeezing of cement, monitoring of well pressure and injecting balance fluid.
