The casing head assembly is the joint between the first casing string and the blowout preventer group or the wellhead. It is used to fix the wellhead of the drilling well, connect the wellhead casing string, and support the technical casing and oil layer casing. Gravity seals the annular space between each layer of pipes, providing transitional connections for the installation of blowout preventers, tubing heads, and Christmas trees. Through the two side ports on the casing head body, mud replenishment, monitoring and filling balance can be performed Liquid and other construction operations.
A casing hanger is also installed in the casing head to hang casing strings of corresponding specifications and seal the annular gap.
The side outlet can be connected with wire flange or thread according to customer requirements. The wire flange outlet has corresponding VR thread.
