The casing head is a component that connects the casing and various well tubing heads. To support the gravity of the technical casing and reservoir casing, seal the annular space between the casing layers, provide a transition connection for the installation of upper wellhead devices such as the blowout preventer, tubing head, and tree, and through two side orifices on the casing head itself, perform additional cement squeeze, monitor well sinking, and inject balancing fluid.
