Casing head

Casing head

The casing head is used to fix the wellhead of the drilling well, connect the wellhead casing string, support the gravity of the technical casing and the oil layer casing, seal the annular space between each layer of pipes, provide transitional connections for the installation of blowout preventers, oil pipe heads, and Christmas trees. Through the two side ports on the casing head body, construction operations such as squeezing mud, monitoring, and adding balance fluid can be carried out.
