Casing Head

The casing head is a core component of wellhead equipment, primarily used to connect casing strings of different specifications downhole. It also enables wellhead pressure control, sealing, and connection for subsequent operations.
As the core hub for suspending and fixing casing strings, the 6A casing head can accurately suspend surface casings, intermediate casings, and production casings during the completion phase of conventional onshore oil wells, gas wells, and unconventional oil and gas wells (such as shale gas and tight oil wells). It ensures that the concentricity of multi-section casing strings meets the requirements, providing support for the formation of a stable "wellbore channel" downhole.
